How to find the length of a string in Python

Educative Answers Team

There are two methods to find the length of a string in Python.

Using the len() method

To calculate the length of a string in Python, you can use the built-in len() method.

It takes a string as a parameter and returns an integer as the length of that string. For example len(“educative”) will return 9 because there are 9 characters in “educative”.

Using the for loop

If you don’t want to use the len() method, you can calculate the length by iterating the string using a for loop and incrementing a counter variable in every iteration. The following code shows how this is done:

counter = 0
for c in "educative": # traverse the string “educative”
    counter+=1 #increment the counter
print (counter) # outputs the length (9) of the string “educative”

Here’s how this method works:
