You can use string.translate and string.maketrans instead.

In Python 1.5:
  exclamation = 'nu'
  exclamation = string.replace(exclamation, 'u', 'i')

In Python 1.4 (and earlier):
  exclamation = 'nu'
  knights_map = string.maketrans('u', 'i')
  exclamation = string.translate(exclamation, knights_map)
