Getting the length of a list in Python

In this tutorial, we are going to learn about how to get the length of list in Python.

The length of a list means the total number of elements present in it.

Using the len() function

To get the length of a list, we can use the built-in len() function in Python.

The len() function takes the list as an argument and returns the number of elements in it.

Here is an example, that gets the length of a fruits list:

fruits = ["apple", "banana", "grapes"]
length = len(fruits)

print(length)

Output:

3

If you don’t like to use the len() function, we can also calculate it manually by using the for loop.

fruits = ["apple", "banana", "grapes"]
counter = 0
for element in fruits:
    counter+=1 #each iteration increment the counter

print (counter) # 3
