Timing it is almost no work, though:
>>> import timeit
>>> timeit.Timer("'a/b/c/'[:-1]").timeit()
0.23856551600831949
>>> timeit.Timer("'a/b/c/'.rstrip('/')").timeit()
0.74258655778876914
The obvious reason for the former to be faster (although I haven't checked
to see whether it's true) is because the latter checks for a specific
character, whereas the former just snips it off whatever it is.
