Introduction to functions in Python and applying them to write shorter and more understandable code.&lt;br /&gt;
Assumes that VPython is [http://www.physicsbook.gatech.edu/VPython installed] and you understand the [http://www.physicsbook.gatech.edu/VPython_basics basics] of programming in Python.&lt;br /&gt;
&lt;br /&gt;
==Summary==&lt;br /&gt;
&lt;br /&gt;
Functions at a high level are used to perform a certain task. Functions can accept a number of inputs (also &amp;quot;arguments&amp;quot; or &amp;quot;parameters&amp;quot;) and can give back 0 or 1 output values. Furthermore, they make code much easier to understand by encapsulating a task in a single line of code instead of being repeated over and over again.&lt;br /&gt;
&lt;br /&gt;
Whenever you type &amp;lt;code&amp;gt;print(5)&amp;lt;/code&amp;gt;, you are calling a function called &amp;lt;code&amp;gt;print&amp;lt;/code&amp;gt; with an argument of &amp;lt;code&amp;gt;5&amp;lt;/code&amp;gt;. This page will describe the basics of functions and how to &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Basic of Functions==&lt;br /&gt;
&lt;br /&gt;
===Basic Python function syntax===&lt;br /&gt;
Functions can be defined with the def keyword followed by the function name and a colon.&lt;br /&gt;
The &amp;lt;code&amp;gt;return&amp;lt;/code&amp;gt; keyword can be used for a function to &amp;quot;give back&amp;quot; a result.&lt;br /&gt;
&lt;br /&gt;
 def functionName(argumentOne, argumentTwo):&lt;br /&gt;
     functionReturnValue = argumentOne + argumentTwo&lt;br /&gt;
     return functionReturnValue&lt;br /&gt;
&lt;br /&gt;
===Example function===&lt;br /&gt;
&lt;br /&gt;
 # This function adds three numbers together and gives back the result using the return keyword&lt;br /&gt;
 def addNumbers(a, b, c):&lt;br /&gt;
     return a + b + c&lt;br /&gt;
&lt;br /&gt;
===Example use of a function===&lt;br /&gt;
 # Calls the function addNumbers with the arguments 1, 2 and 4&lt;br /&gt;
 result = addNumbers(1, 2, 4)&lt;br /&gt;
&lt;br /&gt;
==Writing your own Functions==&lt;br /&gt;
Writing a function for a task instead of copy and pasting code makes your program much easier to understand and debug. The best way to illustrate this is with an example.&lt;br /&gt;
&lt;br /&gt;
For this example, we will create a function to calculate the electric field created by a point charge.&lt;br /&gt;
&lt;br /&gt;
As a reminder, this is the formula we are modeling:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\overrightarrow{E}=\frac{1}{4πε_0}  \frac{q}{|\overrightarrow{r}|^2} \hat r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
First, we ask what do we need to calculate the electric field?&lt;br /&gt;
* &amp;lt;math&amp;gt;q&amp;lt;/math&amp;gt; - the charge of the source&lt;br /&gt;
* &amp;lt;math&amp;gt;\overrightarrow{r}&amp;lt;/math&amp;gt; - the distance from the source to the electric field&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;q&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\overrightarrow{r}&amp;lt;/math&amp;gt; will be the two arguments to our function which will look like this:&lt;br /&gt;
&lt;br /&gt;
 # Calculates the electric field at a given vector away from the charge&lt;br /&gt;
 def electricField(q, r):&lt;br /&gt;
     electricConstant = 9e9 # 1/(4 * π * e0)&lt;br /&gt;
     return electricConstant * q * r.norm() / r.mag2&lt;br /&gt;
&lt;br /&gt;
===Using the function===&lt;br /&gt;
&lt;br /&gt;
We can apply functions to make our code shorter and easier to understand. Here is some example code that we will shorten with functions.&lt;br /&gt;
&lt;br /&gt;
 # Calculate the eletric field in two different places&lt;br /&gt;
 charge = 1.6e-19&lt;br /&gt;
 origin = vector(0,0,0)&lt;br /&gt;
 &lt;br /&gt;
 point1 = vector(-10, 5, 15)&lt;br /&gt;
 point2 = vector(20, -5, 12)&lt;br /&gt;
 &lt;br /&gt;
 field1 = 9e9 * charge * point1.norm() / point1.mag2&lt;br /&gt;
 field2 = 9e9 * charge * point2.norm() / point2.mag2&lt;br /&gt;
&lt;br /&gt;
We can use a function in the last 2 lines to reduce the duplicated code to the following&lt;br /&gt;
&lt;br /&gt;
 field1 = electricField(charge, point1)&lt;br /&gt;
 field2 = electricField(charge, point2)&lt;br /&gt;

&lt;br /&gt;
Introduction to functions in Python and applying them to write shorter and more understandable code.&lt;br /&gt;
&lt;br /&gt;
==Summary==&lt;br /&gt;
&lt;br /&gt;
Functions at a high level are used to perform a certain task. Functions can accept a number of inputs (also &amp;quot;arguments&amp;quot; or &amp;quot;parameters&amp;quot;) and can give back 0 or 1 output values. Furthermore, they make code much easier to understand by encapsulating a task in a single line of code instead of being repeated over and over again.&lt;br /&gt;
&lt;br /&gt;
Whenever you type &amp;lt;code&amp;gt;print(5)&amp;lt;/code&amp;gt;, you are calling a function called &amp;lt;code&amp;gt;print&amp;lt;/code&amp;gt; with an argument of &amp;lt;code&amp;gt;5&amp;lt;/code&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Basic of Functions==&lt;br /&gt;
&lt;br /&gt;
===Basic Python function syntax===&lt;br /&gt;
Functions can be defined with the def keyword followed by the function name and a colon.&lt;br /&gt;
The &amp;lt;code&amp;gt;return&amp;lt;/code&amp;gt; keyword can be used for a function to &amp;quot;give back&amp;quot; a result.&lt;br /&gt;
&lt;br /&gt;
 def functionName(argumentOne, argumentTwo):&lt;br /&gt;
     functionReturnValue = argumentOne + argumentTwo&lt;br /&gt;
     return functionReturnValue&lt;br /&gt;
&lt;br /&gt;
===Example function===&lt;br /&gt;
&lt;br /&gt;
 # This function adds three numbers together and gives back the result using the return keyword&lt;br /&gt;
 def addNumbers(a, b, c):&lt;br /&gt;
     return a + b + c&lt;br /&gt;
&lt;br /&gt;
===Example use of a function===&lt;br /&gt;
 # Calls the function addNumbers with the arguments 1, 2 and 4&lt;br /&gt;
 result = addNumbers(1, 2, 4)&lt;br /&gt;
&lt;br /&gt;
==Writing your own Functions==&lt;br /&gt;
Writing a function for a task instead of copy and pasting code makes your program much easier to understand and debug. The best way to illustrate this is with an example.&lt;br /&gt;
&lt;br /&gt;
For this example, we will create a function to calculate the electric field created by a point charge.&lt;br /&gt;
&lt;br /&gt;
As a reminder, this is the formula we are modeling:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\overrightarrow{E}=\frac{1}{4πε_0}  \frac{q}{|\overrightarrow{r}|^2} \hat r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
First, we ask what do we need to calculate the electric field?&lt;br /&gt;
* &amp;lt;math&amp;gt;q&amp;lt;/math&amp;gt; - the charge of the source&lt;br /&gt;
* &amp;lt;math&amp;gt;\overrightarrow{r}&amp;lt;/math&amp;gt; - the distance from the source to the electric field&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;q&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\overrightarrow{r}&amp;lt;/math&amp;gt; will be the two arguments to our function which will look like this:&lt;br /&gt;
&lt;br /&gt;
 # Calculates the electric field at a given vector away from the charge&lt;br /&gt;
 def electricField(q, r):&lt;br /&gt;
     electricConstant = 9e9 # 1/(4 * π * e0)&lt;br /&gt;
     return electricConstant * q * r.norm() / r.mag2&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Using the function===&lt;br /&gt;
&lt;br /&gt;
We can apply functions to make our code shorter and easier to understand. Here is some example code that we will shorten with functions.&lt;br /&gt;
&lt;br /&gt;
 # Calculate the eletric field in two different places&lt;br /&gt;
 charge = 1.6e-19&lt;br /&gt;
 origin = vector(0,0,0)&lt;br /&gt;
 &lt;br /&gt;
 point1 = vector(-10, 5, 15)&lt;br /&gt;
 point2 = vector(20, -5, 12)&lt;br /&gt;
 &lt;br /&gt;
 field1 = 9e9 * charge * point1.norm() / point1.mag2&lt;br /&gt;
 field2 = 9e9 * charge * point2.norm() / point2.mag2&lt;br /&gt;
&lt;br /&gt;
We can use a function in the last 2 lines to reduce the duplicated code to the following&lt;br /&gt;
&lt;br /&gt;
 field1 = electricField(charge, point1)&lt;br /&gt;
 field2 = electricField(charge, point2)&lt;br /&gt;

&lt;br /&gt;
===Basic Python function syntax===&lt;br /&gt;
Functions can be defined with the def keyword followed by the function name and a colon.&lt;br /&gt;
The &amp;lt;code&amp;gt;return&amp;lt;/code&amp;gt; keyword can be used for a function to &amp;quot;give back&amp;quot; a result.&lt;br /&gt;
&lt;br /&gt;
 def functionName(argumentOne, argumentTwo):&lt;br /&gt;
     functionReturnValue = argumentOne + argumentTwo&lt;br /&gt;
     return functionReturnValue&lt;br /&gt;
&lt;br /&gt;
===Example function===&lt;br /&gt;
&lt;br /&gt;
 # This function adds three numbers together and gives back the result using the return keyword&lt;br /&gt;
 def addNumbers(a, b, c):&lt;br /&gt;
     return a + b + c&lt;br /&gt;
&lt;br /&gt;
===Example use of a function===&lt;br /&gt;
 # Calls the function addNumbers with the arguments 1, 2 and 4&lt;br /&gt;
 result = addNumbers(1, 2, 4)&lt;br /&gt;
&lt;br /&gt;
==Code Reuse==&lt;br /&gt;
Writing a function for a task instead of copy and pasting code makes your program much easier to understand and debug. The best way to illustrate this is with an example.&lt;br /&gt;
&lt;br /&gt;
For this example, we will create a function to calculate the electric field created by a point charge.&lt;br /&gt;
&lt;br /&gt;
As a reminder, this is the formula we are modeling:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;E=\frac{-q}{|r̂|^2}r̂&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
First, we ask what do we need to calculate the electric field?&lt;br /&gt;
&lt;br /&gt;
{{hidden&lt;br /&gt;
|Show arguments&lt;br /&gt;
|q - the charge of the source&amp;lt;br/&amp;gt; r - the distance from the source to the electric field&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
 # Calculates the eletric field at a given vector away from the charge&lt;br /&gt;
 def eletricField(q, r):&lt;br /&gt;
     eletricConstant = 9e9 # 1/(4 * pi * ε0)&lt;br /&gt;
     return eletricConstant * q * r.norm() / r.mag2&lt;br /&gt;

Introduction to functions in Python and applying them to write shorter and more understandable code.&lt;br /&gt;
&lt;br /&gt;
==Summary==&lt;br /&gt;
&lt;br /&gt;
Functions at a high level are used to perform a certain task. Functions can accept a number of inputs (also &amp;quot;arguments&amp;quot; or &amp;quot;parameters&amp;quot;) and can give back 0 or 1 output values. Furthermore, they make code much easier to understand by encapsulating a task in a single line of code instead of being repeated over and over again.&lt;br /&gt;
&lt;br /&gt;
Whenever you type &amp;lt;code&amp;gt;print(5)&amp;lt;/code&amp;gt;, you are calling a function called &amp;lt;code&amp;gt;print&amp;lt;/code&amp;gt; with an argument of &amp;lt;code&amp;gt;5&amp;lt;/code&amp;gt;. &lt;br /&gt;

&lt;br /&gt;
 def functionName(argumentOne, argumentTwo):&lt;br /&gt;
     functionReturnValue = argumentOne + argumentTwo&lt;br /&gt;
     return functionReturnValue&lt;br /&gt;
&lt;br /&gt;

 # This function adds three numbers together and gives back the result using the return keyword&lt;br /&gt;

Introduction to functions in Python and applying them to write shorter and more understandable code.&lt;br /&gt;
&lt;br /&gt;
==The Main Idea==&lt;br /&gt;
&lt;br /&gt;
The main idea of this page is to serve as an aid for future physics students in writing python code during lab. Python, especially for students who are not very experienced with coding, can be a little confusing and sometimes stressful. This page should help give students the information that they would have to look up outside of the lab instructions but all in one place so that they can focus on the physics aspect of the course and not take too much time worrying about the coding in lab.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Basic Functions==&lt;br /&gt;
&lt;br /&gt;
===Basic Python function syntax===&lt;br /&gt;
&lt;br /&gt;
Functions at a high level are used to perform a certain task. They can take anywhere number of inputs and can return 0 or 1 outputs.&lt;br /&gt;
Functions can be defined with the &amp;lt;code&amp;gt;def&amp;lt;/code&amp;gt; keyword followed by the function name and a colon.&lt;br /&gt;
The &amp;lt;code&amp;gt;return&amp;lt;/code&amp;gt; keyword can be used for a function to &amp;quot;give back&amp;quot; a result.&lt;br /&gt;
&lt;br /&gt;
 def functionName(argumentOne, argumentTwo):&lt;br /&gt;
     functionReturnValue = argumentOne + argumentTwo&lt;br /&gt;
     return functionReturnValue&lt;br /&gt;
&lt;br /&gt;
===Example function===&lt;br /&gt;
&lt;br /&gt;
 # This function adds three numbers together and gives back the result using the return keyword&lt;br /&gt;
 def addNumbers(a, b, c):&lt;br /&gt;
     return a + b + c&lt;br /&gt;
&lt;br /&gt;
===Example use of a function===&lt;br /&gt;
 # Calls the function addNumbers with the arguments 1, 2 and 4&lt;br /&gt;
 result = addNumbers(1, 2, 4)&lt;br /&gt;
&lt;br /&gt;
==Connectedness==&lt;br /&gt;
VPython is an important tool in PHYS 2211 and PHYS 2212 because it is able to take a very abstract concept and give a visual explanation to the student. &lt;br /&gt;

&lt;div&gt;__NOTOC__&lt;br /&gt;
Welcome to the Georgia Tech Wiki for Intro Physics.  This resources was created so that students can contribute and curate content to help those with limited or no access to a textbook.  When reading this website, please correct any errors you may come across. If you read something that isn&#039;t clear, please consider revising it!&lt;br /&gt;
&lt;br /&gt;
Looking to make a contribution?&lt;br /&gt;
#Pick a specific topic from intro physics&lt;br /&gt;
#Add that topic, as a link to a new page, under the appropriate category listed below by editing this page.&lt;br /&gt;
#Copy and paste the default [[Template]] into your new page and start editing.&lt;br /&gt;
&lt;br /&gt;
Please remember that this is not a textbook and you are not limited to expressing your ideas with only text and equations.  Whenever possible embed: pictures, videos, diagrams, simulations, computational models (e.g. Glowscript), and whatever content you think makes learning physics easier for other students.&lt;br /&gt;
&lt;br /&gt;
== Source Material ==&lt;br /&gt;
All of the content added to this resource must be in the public domain or similar free resource.  If you are unsure about a source, contact the original author for permission. That said, there is a surprisingly large amount of introductory physics content scattered across the web.  Here is an incomplete list of intro physics resources (please update as needed).&lt;br /&gt;
* A physics resource written by experts for an expert audience [https://en.wikipedia.org/wiki/Portal:Physics Physics Portal]&lt;br /&gt;
* A wiki book on modern physics [https://en.wikibooks.org/wiki/Modern_Physics Modern Physics Wiki]&lt;br /&gt;

* The Open Source Physics project is a collection of online physics resources [http://www.opensourcephysics.org/ OSP]&lt;br /&gt;
* A resource guide compiled by the [http://www.aapt.org/ AAPT] for educators [http://www.compadre.org/ ComPADRE]&lt;br /&gt;
&lt;br /&gt;
== Organizing Categories ==&lt;br /&gt;
These are the broad, overarching categories, that we cover in two semester of introductory physics.  You can add subcategories or make a new category as needed.  A single topic should direct readers to a page in one of these catagories.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;I had created the [[VPython Functions and Lists]] page but then decided that was a bigger topic and instead created the [[VPython Functions]] page. &lt;br /&gt;
You claimed that new page before I could. Are you set on making that page? If so i&#039;m happy to do VPython Lists instead.&lt;br /&gt;
I&#039;m not sure if this will work to contact you. I&#039;ll try a different method if not. &lt;br /&gt;

&lt;div&gt;__NOTOC__&lt;br /&gt;
Welcome to the Georgia Tech Wiki for Intro Physics.  This resources was created so that students can contribute and curate content to help those with limited or no access to a textbook.  When reading this website, please correct any errors you may come across. If you read something that isn&#039;t clear, please consider revising it!&lt;br /&gt;
&lt;br /&gt;
Looking to make a contribution?&lt;br /&gt;
#Pick a specific topic from intro physics&lt;br /&gt;
#Add that topic, as a link to a new page, under the appropriate category listed below by editing this page.&lt;br /&gt;
#Copy and paste the default [[Template]] into your new page and start editing.&lt;br /&gt;
&lt;br /&gt;
Please remember that this is not a textbook and you are not limited to expressing your ideas with only text and equations.  Whenever possible embed: pictures, videos, diagrams, simulations, computational models (e.g. Glowscript), and whatever content you think makes learning physics easier for other students.&lt;br /&gt;
&lt;br /&gt;
== Source Material ==&lt;br /&gt;
All of the content added to this resource must be in the public domain or similar free resource.  If you are unsure about a source, contact the original author for permission. That said, there is a surprisingly large amount of introductory physics content scattered across the web.  Here is an incomplete list of intro physics resources (please update as needed).&lt;br /&gt;
* A physics resource written by experts for an expert audience [https://en.wikipedia.org/wiki/Portal:Physics Physics Portal]&lt;br /&gt;
* A wiki book on modern physics [https://en.wikibooks.org/wiki/Modern_Physics Modern Physics Wiki]&lt;br /&gt;

&lt;br /&gt;
== Organizing Categories ==&lt;br /&gt;
These are the broad, overarching categories, that we cover in two semester of introductory physics.  You can add subcategories or make a new category as needed.  A single topic should direct readers to a page in one of these catagories.&lt;br /&gt;

&lt;div&gt;__NOTOC__&lt;br /&gt;
Welcome to the Georgia Tech Wiki for Intro Physics.  This resources was created so that students can contribute and curate content to help those with limited or no access to a textbook.  When reading this website, please correct any errors you may come across. If you read something that isn&#039;t clear, please consider revising it!&lt;br /&gt;
&lt;br /&gt;
Looking to make a contribution?&lt;br /&gt;
#Pick a specific topic from intro physics&lt;br /&gt;
#Add that topic, as a link to a new page, under the appropriate category listed below by editing this page.&lt;br /&gt;
#Copy and paste the default [[Template]] into your new page and start editing.&lt;br /&gt;
&lt;br /&gt;
Please remember that this is not a textbook and you are not limited to expressing your ideas with only text and equations.  Whenever possible embed: pictures, videos, diagrams, simulations, computational models (e.g. Glowscript), and whatever content you think makes learning physics easier for other students.&lt;br /&gt;
&lt;br /&gt;
== Source Material ==&lt;br /&gt;
All of the content added to this resource must be in the public domain or similar free resource.  If you are unsure about a source, contact the original author for permission. That said, there is a surprisingly large amount of introductory physics content scattered across the web.  Here is an incomplete list of intro physics resources (please update as needed).&lt;br /&gt;
* A physics resource written by experts for an expert audience [https://en.wikipedia.org/wiki/Portal:Physics Physics Portal]&lt;br /&gt;
* A wiki book on modern physics [https://en.wikibooks.org/wiki/Modern_Physics Modern Physics Wiki]&lt;br /&gt;

&lt;br /&gt;
== Organizing Categories ==&lt;br /&gt;
These are the broad, overarching categories, that we cover in two semester of introductory physics.  You can add subcategories or make a new category as needed.  A single topic should direct readers to a page in one of these catagories.&lt;br /&gt;
