How to Remove Substring from a String in Python

In Python, a string can be thought of as a list of individual characters.
This means that we can easily remove a substring from a string.
In this post, we'll look at how you can remove a substring from a string in Python.
Using str.replace()
The most straightforward way to remove a substring from a string is to use the str.replace()
method.
This method is called on the string that you want to remove the substring from, and takes two arguments:
- The substring you want to remove
- The string you want to replace the substring with
Let's first define the string we want to work on:
string = "hello world"
print(string)
hello world
Now, let's remove the substring "world" from the string:
string = "hello world"
string = string.replace("world", "")
print(string)
hello
The str.replace()
method returns a new string with the substring removed, so we can just assign the result to the same variable.
Keep in mind that strings in Python are immutable, so once you create a string, you can't change it.
Conclusion
In this post, we looked at how you can remove a substring from a string in Python.
Simply use the str.replace()
method to remove a substring from a string by replacing it with an empty string.
