Python3.x Python3 replace() Method

Python3 Strings

---

Description

The replace() method replaces occurrences of a substring with another substring in a string. If a third parameter max is specified, the replacement will not exceed max times.

Syntax

Here is the syntax for the replace() method:

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

Parameters

• old -- The substring to be replaced.
• new -- The new substring to replace the old substring.
• max -- Optional. The maximum number of replacements to make.

Return Value

Returns a new string with all occurrences of the old substring replaced by the new substring. If the third parameter max is specified, the replacement will not exceed max times.

Example

The following example demonstrates the usage of the replace() function:

Example

#!/usr/bin/python3

str = "www.w3cschool.cc"
print("Old address of Tutorial: ", str)
print("New address of Tutorial: ", str.replace("w3cschool.cc", ""))

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

The output of the above example is as follows:

Old address of Tutorial:  www.w3cschool.cc
New address of Tutorial:  www.
thwas was string example....wow!!!
