Example 2: difference between arrays and lists in python

lists and arrays are used in Python to store data(any data type- strings, integers etc), both can be indexed and iterated also. ... Arrays need to be declared whereas lists do not need declaration because they are a part of Python's syntax. This is the reason lists are more often used than arrays.
