Replace String in Python

 

At times we need to replace strings in a statement or in a file. We will see here how we can replace a string with another in python.

To Replace a string in python, we can user replace() method.

Example: 

        old_string = "This is the old string."

        new_string = old_string.replace("old", "new")

        print(new_string)

This can also be achieved by using the 're' module of python, which is used for advanced string and regex replacements.

Code: 

    

        import re

        old_string = "This is the old string."

        new_string = re.sub("old", "new", old_string)

        print(new_string)

        Output: This is the new string.
