List

In Python, a list is the main data structure used to store a mutable sequence of elements. The sequence of data elements stored in the list need not be of the same type.

To create a list, the data elements need to be enclosed in [ ] and they need to be separated by a comma. For example, the following code creates four data elements together that are of different types:

>>> aList = ["John", 33,"Toronto", True]
>>> print(aList)
['John', 33, 'Toronto', True]Ex

In Python, a list is a handy way of creating one-dimensional writable data structures that are needed especially at different internal stages of algorithms.
