Python Standard Library

The regsub Module

(Obsolete) The regsub module, shown in Example 14-33, provides string replacements, based on regular expressions. New code should use the re module’s replace function instead.

Example 14-33. 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.
