I tried the same routine on a machine with 1.5.1 and it worked fine,
you're right about the version being the problem. Thanks for your help.

I believe string.replace came with 1.5.

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)
