We first find the length of … Lists provide a convenient way of storing elements. Length of List in Python Lists are a data structure commonly used in Python. len () works in O (1) time as list is an object and has a member to store its size. The len () method in Python finds the size of the list which returns the number of elements in the given list. data = [7, 15, 33, 40] Get_List_length = len (data) print ("Python list size will be ", Get_List_length) Getting Length of The List using Python Example.
