Python List

A list is a data type that can hold more than one value. Some important properties about list include:

  • Lists are ordered
  • They can contain mixed types of object, for example: floats, string, intergers ect
  • List are mutable and dynamics
  • List is ordered by index starting with zero

Here is what a list would look like in python 3

>>> fruit = ['apple', 'berry', 'grapes']
>>> fruit
['apple', 'berry', 'grapes']
>>>

You can add, remove items or elements to a list. This makes list dynamic. Here is a example of how to do it by using the built-in methods to add and remove more item from fruit list.

>>> fruit.append('banana')
>>> fruit
['apple', 'berry', 'grapes', 'banana']
>>>

Append is used to add a object however you cannot place the item where you want it to be, if you want to place your object you can use the method insert.

>>> fruit.insert(1, 'orange')
>>> fruit
['apple', 'orange', 'berry', 'grapes', 'banana']
>>>

If you are wondering why I put 1 when the orange is the second item the reason is that the item is listed from 0 to any number this is called index.
