How to Create Count the Number of Digits in Python

In this tutorial, we will create a "How to Count the Number of Digits in Python". We will cover the creation of a program that counts the number of digits. The main goal here is to understand the concept of counting digits from numbers. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you is how to count digits from numbers. I will do my best to provide you with the easiest method of creating this program, called "Count the Number of Digits". So, let's start with the coding.

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console of counting the number of digits. To do this, simply copy and paste these blocks of code into the IDLE text editor.
  1. while True:
  2. ret=False
  4. print("\n\n================= Count the Number of Digits in Python =================\n\n")
  6. num = int(input("Enter a number: "))
  8. count = 0
  10. while num != 0:
  11. num //= 10
  12. count += 1
  14. print("Number of digits: " + str(count))
  16. user_input=input("\n\nTry again? (Yes/No): ")
  17. print("\n\n")
  18. if user_input.lower()=='no':
  19. print("Exit program.")
  20. break
  22. elif user_input.lower()=='yes':
  23. ret=True
  25. else:
  26. print("Wrong input.")
  27. ret=True
  30. if ret:
  31. continue

In the provided code, the first step is to use a while loop to enclose all the code to ensure the continuity of the program. Next, we set variables for the user input and for counting the digits. Lastly, we use a while loop with an argument that counts the number of digits within the provided number.
