get the number of elements in a list python code example

Example 1: python find the number of elements in a list

list1 = [2,3,4,3,10,3,5,6,3]
elm_count = list1.count(3)
print('The count of element: 3 is ', elm_count)

Example 2: 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 3: how to find length of list python

my_list = [1,2,3,4,5,6,7,8,9,10]

length_of_list = len(my_list)

Example 4: count number items in list python

mylist = ["abc", "def", "ghi", "jkl", "mno", "pqr"]

print(len(mylist))

# output 6
