list of string combinations

[Skaperen]

the bash shell for Unix has a feature that allows using a text token like {a,b}{c,d}{e,f} and produces all combinations as if ace acf ade adf bce bcf bde bdf had been used in its place. has anyone seen or written a Python function that can do this to a string, maybe returning a list, such as:

string_combos('{a,b}{c,d}{e,f}') => ['ace','acf','ade','adf','bce','bcf','bde','bdf']
