Removing a Substring from a String in Python

To remove a substring from a string in Python, you can use various methods such as slicing, the replace() method, or regular expressions. Here's a step-by-step explanation for each method:

Using Slicing

You can use slicing to remove a substring from a string by creating a new string that excludes the substring. Here's an example:

original_string = "This is the original string"
substring_to_remove = "original "
new_string = original_string.replace(substring_to_remove, "")
print(new_string)

This will output:

This is the string

Using the replace() Method

The replace() method can also be used to remove a substring from a string by replacing it with an empty string. Here's an example:

original_string = "This is the original string"
substring_to_remove = "original "
new_string = original_string.replace(substring_to_remove, "")
print(new_string)

This will output:

This is the string

Using Regular Expressions

Regular expressions can be used to remove a substring from a string based on a pattern. Here's an example:

import re
original_string = "This is the original string"
substring_to_remove = "original "
new_string = re.sub(substring_to_remove, "", original_string)
print(new_string)

This will output:

This is the string

These are the different methods you can use to remove a substring from a string in Python. Each method offers flexibility and can be chosen based on the specific requirements of your task.
