How to to Get a Substring of a String in Python

In this tutorial, we will cover How to Get a Substring of a String in Python. The main goal is to understand the concept of getting a substring of a string. We 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 about how to get the substring of a string. I will do my best to provide you with the easiest method of creating this program, called "Get a Substring of a String". 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 getting a substring from a string. 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================= Get a Substring of a String =================\n\n")
  6. my_string = "I love Sourcecodester."
  9. print(my_string[2:6])
  12. print(my_string[2:])
  15. print(my_string[:-1])
  17. user_input=input("\n\nTry again? (Yes/No): ")
  18. print("\n\n")
  19. if user_input.lower()=='no':
  20. print("Exit program.")
  21. break
  23. elif user_input.lower()=='yes':
  24. ret=True
  26. else:
  27. print("Wrong input.")
  28. ret=True
  31. if ret:
  32. continued

In the provided code, we first use a while loop to encapsulate all the code, then set a variable for the string we will use. To get the substring of a string, we use square brackets [] and insert a pair of indices to determine the scale you want to substring.
