How to find the sum of the numbers in the given string in Python

In this tutorial, We will see How to find the sum of the numbers in the given string in Python. This tutorial is based on the Regular expression or regex module i.e re module. So, to solve this problem we have to understand the regular expression module.

What is the regular expression module in Python?

Python has an inbuilt re module which allows us to solve the various problem based on pattern matching and string manipulation.

Find all integer values in the given string by regular expression in Python

Before going to find the sum of the numbers in the given string, We have to learn how to find all numbers in the given string by using re module. So, let’s start to understand

import re


['17', '22', '8']

Here, We include re module by using the import function and assume the input provided from the user is My17name22is8bipin. By using the findall function from the re module we separated the number as a list. In the regular expression, ‘\d+’ used to find all integer value in the given input from the user.

As we have seen that the number is in list form that why for summation of all integer we have to run a for loop in the program. Now we are going to write the Python code.

Python Code:

import re
for j in number:
