This page is about using lists in VPython to do computing at a scale larger than one or two objects.

VPython List

State, in your own words, the main idea for this topic

Types of Nests

Lists of Numbers

The most basic list is one that has numbers in it. The list of numbers may contain integers, floats, or both. Example: numList = [1,2,3.4,5]

Lists of Strings

Lists can also be comprised of words (strings). These words must have "" surrounding them for the word to be considered a string and for the computer to accept it. Example: strList = ["lists","are","super","cool"]

Lists of Both

Lists don't have to be made up of the same type of variable. For example, the list ["twenty",20,5,"five"] is a valid list.

Lists of Lists

Lists can also contain lists within themselves. These are called nested loops. Example: [1,"nest",[1,2]]

Empty Nests

Empty nests are commonly used to initiate a variable and avoid program errors when calling upon that empty list. They generally have variables appended into them and grow throughout the program.
