Python is a dynamic programming language renowned for its simplicity and readability. As Python programmers, one common task you may need to accomplish is the removal of a specific digit from a number.

Regardless of whether you’re a beginner or a professional developer, this tutorial will guide you through the process of removing a digit from a number in Python.

Step 1: Convert the Number to a String

In Python, numbers don’t provide the flexibility needed to remove a digit. However, strings do. Thus, the first step requires the conversion of the number into a string. In Python, you can use the str() function to convert an integer into a string. See the snippet below:

Step 2: Remove the Digit

With our number now a string, we can use the built-in replace() method to remove the digit. This method replaces a specified value with another specified value. In our case, we’ll replace the desired digit with an empty string, effectively removing it. Here’s an example:

Step 3: Convert the Result Back to a Number

Finally, after removing the desired digit, we’ll need to convert our string back to a number for future computations. To do this, Python provides us with the int() function:

Output

Below is our output after the execution of the above steps:

Conclusion

Python’s built-in functions and string manipulation capabilities make tasks like removing a digit from a number straightforward. This tutorial guided you through the process step-by-step.

With practice and application, you should be able to effortlessly remove any specific digit from a number in Python. Make sure to thoroughly understand each part of the process and keep coding!
