Or it might be preferable to use a dictionary:
 
>>> gender = 'f'
>>> verbose = {'m': 'male', 'f': 'female'}.get(gender, 'unknown')
>>> verbose
'female'
>>> gender = 'm'
>>> verbose = {'m': 'male', 'f': 'female'}.get(gender, 'unknown')
>>> verbose
'male'
>>> gender = 'x' 
>>> verbose = {'m': 'male', 'f': 'female'}.get(gender, 'unknown')
>>> verbose
'unknown'

IMHO, it's no less readable and a bit more flexible.
