List Items of Different Types Python lists are very flexible. We can also store data of different data types in a list. For example, # a list containing strings, numbers and another liststudent = ['Jack',32,'Computer Science', [2,4]]print(student)# an empty listempty_list = []print...
A Python list is ordered, indexed (indices start at 0), mutable, heterogeneous (items need not be of the same type) and written CSV in square brackets.
the average is calculated by getting the sum of the elements in the list and dividing it by the count of elements. The sum() is a Python in-built function that will return the totalsum of elements from the listand the len() will return the total number of elements present in...
