The regsub module

(Obsolete). This module provides string replacements, based on regular expressions. New code should use the re module’s replace function instead.

Example: Using the regsub module

# File: regsub-example-1.py

import regsub

text = "Well, there's spam, egg, sausage and spam."

print regsub.sub("spam", "ham", text) # just the first
print regsub.gsub("spam", "bacon", text) # all of them

Well, there's ham, egg, sausage and spam.
Well, there's bacon, egg, sausage and bacon.
