How To Get Second Digit Of A Number In Python

In this tutorial, we will learn how to get the second digit of a number in Python.

Python has a rich ecosystem of built-in functions and libraries which makes it easy to perform several operations on numbers.

We will use Python’s built-in functions to get the second digit of a number.

Step 1: Understanding the concepts of integer and string

To get the second digit of a number, we will first need to understand the difference between an integer and a string. An integer is a whole number while a string is a sequence of characters. In Python, you can convert an integer to a string using the str() function and a string to an integer using the int() function.

Step 2: Convert the number to a string

To get the second digit of a number, we must first convert the number to a string. This way, we can access individual digits using indexing. Here’s how you can convert an integer to a string:

Step 3: Get the second digit using indexing

Once you have converted the number to a string, you can get the second digit using indexing. In Python, indexing starts from 0. So, to get the second digit, we will use index 1.

Step 4: Convert the second digit back to an integer

After getting the second digit as a string, we can convert it back to an integer using the int() function:

Now, let’s combine all the steps above to create a function that returns the second digit of a number.

Step 5: Test the function

Now, let’s test the function with a few examples:

Output:

The second digit of 12345 is 2
The second digit of 5678 is 6
The second digit of 9 is None

Conclusion

In this tutorial, we have learned how to get the second digit of a number in Python using the built-in functions for converting integers to strings and vice versa. This is a simple yet powerful technique you can use when you need to manipulate digits in a number.
