how many items in a list python code example
Example 1: 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
Example 2: number of elements in list in python
# List of strings
listOfElems = ['Hello', 'Ok', 'is', 'Ok', 'test', 'this', 'is', 'a', 'test']
len(s)
Example 3: 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)
