Python String replace Method [With Examples]

Python String replace

This article shows you how to use the string.replace() method in Python to replace elements in a string of characters and includes useful examples.

Python String replace Syntax

The replace() function can be called on existing string variables like so:

string.replace(find, new, count)

Where:

  • string is the existing string variable
  • find is the string your want found and replaced
  • new is the text you want to replace the found text
  • count is the number of instances of the found text you want to be replaced, counted from the beginning of the string being searched

Examples

Replacing All Occurrences

myText = "Cars are fast!"
newText = myText.replace("Cars", "Rockets")
print(newText) # Will return "Rockets are fast!"

Replacing Specified Number of Occurrences

This example will replace the first 2 occurrences of red:

myText = "red green red red green red"
newText = myText.replace("red", "blue", 2)
print(newText) # Will return "blue green blue red green red"

Removing Values

Pass an empty string as the second parameter to remove found values:

myText = "red green red red green red"
newText = myText.replace("red", "", 2)
print(newText) # Will return " green  red green red"
