What about this:

 >>> class myFile:
... 	formats=['ps', 'ps2', 'pcl']
... 	for frmt in formats:
... 		exec "def file2%s(self): return '%s'" % (frmt, frmt)
... 	del frmt
...
 >>> dir(myFile)
['__doc__', '__module__', 'file2pcl', 'file2ps', 'file2ps2', 'formats']
 >>> f = myFile()
 >>> f.file2pcl()
'pcl'
 >>>
