python number of elements in list of lists

# Basic syntax:
# Using list comprehension:
sum([len(elem) for elem in list_of_lists])

# Example usage:
# Say you want to count the number of elements in a nested list like:
nested_list = [ [1, 2, 3, 45, 6, 7],
                [22, 33, 44, 55],
                [11, 13, 14, 15] ]

sum([len(elem) for elem in nested_list])
--> 14

python number of elements in a list

list_a = ["Hello", 2, 15, "World", 34] #just the array

number_of_elements = len(list_a)

print("Number of elements in the list: ", number_of_elements)

python list number of elements

list_a = ["Hello", 2, 15, "World", 34]
number_of_elements = len(list_a)
