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 https://www.python.org/downloads/.

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.

while True:
    ret=False
 
    print("\n\n================= Get a Substring of a String =================\n\n")
 
    my_string = "I love Sourcecodester."
 
 
    print(my_string[2:6])
 
 
    print(my_string[2:])
 
 
    print(my_string[:-1])
 
    user_input=input("\n\nTry again? (Yes/No): ")
    print("\n\n")
    if user_input.lower()=='no':
        print("Exit program.")
        break
 
    elif user_input.lower()=='yes':
        ret=True
 
    else:
        print("Wrong input.")
        ret=True
 
 
    if ret:
        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.
