You can convert them to tuples with the `tuple' function:

	aDictionary[tuple(aList)] = aKeyword

This code sample seems to suggest you're trying to do something else, 
however.  If `mykey' is a string, then what you wrote is completely 
valid regardless of whether you converted it to a list or not.

If that was just a thinko while you were asking the question, then the 
reason ([...]) didn't work is that it's just syntactically wrapping a 
list comprehension in parentheses, rather than turning them into a tuple.
