Python counts the number of items in the list

Use the Built-in Python len( ) function or for loop to get the count number of items in the list in Python. Just create an empty List and store some items in the list then use any one method.

Python counts the number of items in the list

A simple example code gets the number of elements in a list.

Built-in Function len()

# List of just integers
list_a = [1, 2, 3, 0]
print(len(list_a))

# List of integers, floats, strings, booleans
list_b = [4, 1.2, "hello world", True]
print(len(list_b))

Output:

Python counts the number of items in the list

Using a for Loop

Declare a counter variable to count the number of elements in the list using a for loop and print the counter after the loop in Python gets terminated.

item_list = [1, 2, 3, 4]
# declare a counter variable
count = 0
 
# iterate on items using for-loop
# and keep increasing the value of count
for i in item_list:
    # increment the value of count
    count = count+1


print("No of elements in the list are:", count)

Output: No of elements in the list are: 4
