Introduction

Today, we’ll be exploring a Python programming problem called “Return a String as an Integer.” This problem allows you to learn some fundamental concepts in Python, such as type conversion.

By the end of this article, you’ll have a better understanding of how to write a simple function to convert a string to an integer.

Problem Statement

The problem we’re trying to solve is as follows:

Create a function that takes a string and returns it as an integer.

Here are some examples of how the function should work:

• string_int("6") ➞ 6
• string_int("1000") ➞ 1000
• string_int("12") ➞ 12

Note: All numbers will be whole and positive.

Step 1: Understanding the Problem

We need to create a function that takes one argument (a string representing a number) and returns the equivalent integer value.

Step 2: Writing the Function
