Perhaps you missed Ian Kelly's correction of Thomas Bach's approach:
d = { k: v for v, k in enumerate(cs) }
def collate(x):
return list(map(d.get, x))
sorted(data, key=collate)
I'd use Ian Kelly's approach. It's not only more compact, it shouldn't
give an exception for a character not in the table. At least, not for
Python 2.x. I'm not sure about Python 3, since it can give an exception
comparing None to int.
