Or even shorter:

Shorter, but wrong.
name = ['fb', 'ph', 'xy'] # oops, bad data
if name[0] in 'mfb':

Bad data should lead to an error as close as possible to the source of the bad
data, and do the wrong thing for a while before blowing up in some unexpected

character, make sure the test will only pass when given a single character.
