replace() is an inbuilt function in Python programming language that returns a copy of the string where all occurrences of a substring is replaced with another substring.
Syntax :
string.replace(old, new, count)
Parameters :
old – old substring you want to replace.
new – new substring which would replace the old substring.count – the number of times you want to replace the old substring with the new substring. (Optional )
Return Value :
It returns a copy of the string where all occurrences of a substring is replaced with another substring.
Note:
- If count is not specified then all the occurences of old substring is replaced with the new substring.
- This method returns the copy of the string i.e. it does not changes the original string.
Below is the code demonstrating replace() :
Example 1:
# Python3 program to demonstrate the # use of replace() method string = "geeks for geeks geeks geeks geeks" # Prints the string by replacing all# geeks by Geeks print(string.replace("geeks", "Geeks")) # Prints the string by replacing only# 3 occurrence of Geeks print(string.replace("geeks", "GeeksforGeeks", 3)) |
Output :
Geeks for Geeks Geeks Geeks Geeks GeeksforGeeks for GeeksforGeeks GeeksforGeeks geeks geeks
Example 2:
# Python3 program to demonstrate the# use of replace() method string = "geeks for geeks geeks geeks geeks" # Prints the string by replacing# e by oprint(string.replace("e", "o")) # Prints the string by replacing only# 3 occurrence of ek by oprint(string.replace("ek", "o", 3)) |
Output:
gooks for gooks gooks gooks gooks geos for geos geos geeks geeks
