This could be
retList.extend([word[pos]+item for item in permuteList])
or in Python 2.4 omit the extra brackets:
retList.extend(word[pos]+item for item in permuteList)
The list comprehension
lst = [word[pos]+item for item in permuteList]
is equivalent to
lst = []
for item in permuteList:
lst.append(word[pos]+item)
PS Don't get too crazy about eliminating intermediate variables, they can make
the code more readable.
