Syntax of list

The List is the same as arrays irrespective it can store different data types in it. We can access the list by using the start and end range which can be altered by using custom step function as the third argument.

Let’s define a variable named myList and declare a list of numbers from 1 to 9 in it.

1. List Slicing

List Slicing means accessing the particular element by index or slice or cut a particular range of elements from the .
