The data type list is an ordered sequence which is mutable and made up of one or more elements.

  • A list can have elements of different data types , such as integer, float, string, tuple or even another list. 
  • A list is very useful to group together elements of mixed data types. 
  • Elements of a list are enclosed in square brackets and are separated by comma. 
  • Like string indices, list indices also start from 0.

Accessing elements in a List

The elements of a list are accessed in the same way as characters are accessed in a string. 

The list items are accessed by referring to the index number in square brackets.
