Programming basics[1]
A list is a data structure in Python that is a mutable, or changeable, ordered sequence of elements. Each element or value that is inside of a list is called an item. Just as strings are defined as characters between quotes, lists are defined by having values between square brackets [ ].[2]
Please be careful as lists can be thought of as analogous to arrays, but they aren't the same thing. Arrays traditionally have a fixed memory size whilst lists have dynamic memory allocation. When you are working in Python, call a list a list. When you are working in PHP or Javascript, call an array an array. When you are working in C, call for help!
Creating a list[edit]
polishAnimals = ['Bison', 'Moose', 'Deer', 'Lynx', 'Wolf', 'Beaver', 'Otter']
accessing a list[edit]
inserting into a list[edit]
deleting a list or deleting an element from a list[edit]
finding an element in a list[edit]
sorting a list[edit]
Do you understand this?[edit]
Standards[edit]
- Construct algorithms using pre- defined sub-programmes, one- dimensional arrays and/or collections.
