Python String replace() Method with example



Hello guys! Welcome back to another section of my tutorial on Python. In this tutorial guide, we are going to be discussing about the Python String replace() method.

The Python string replace() method returns a copy of the string in which occurrences of the old have been replaced with new, which optionally restricts the number of replacements to max.

Syntax

The following below is the syntax for the Python String replace() method -

str.replace(old,  new[,  max] )


Parameter Details

  • old - This is the old substring to be replaced.
  • new - This is the new substring that will replace the old substring.
  • max - If this optional argument is given, only the first count occurrences are replaced.

Return Value

This method returns a copy of the string with all occurrences of substring old replaced by new.

Example

The following below is a simple example -

#!/usr/bin/python

str = "this is string example....wow!!! this is really string"
print str.replace("is", "was")
print str.replace("is", "was", 3)

Output
Below is the output of the above example -

thwas was string example....wow!!! thwas was really string
thwas was string example....wow!!! thwas is really string


Alright guys! This is where we are rounding up for this tutorial post. In my next tutorial, we are going to be discussing about the Python String rfind() method.
