Hmm:
def getchoice(prompt, choices, default):
"""prompt is a format string with a %s where the list of choices
should go, and another %s where the default should go;
choices is a list of choices; default is the default choice"""
assert default in choices
prompt %= ('/'.join(choices), default)
while True:
c = raw_input (prompt)
if not c:
return default
a = [x for x in choices if x.startswith(c)]
if len(a) == 0:
print 'Please choose one of', '/'.join(choices)
elif len(a) > 1:
print 'ambiguous, enter a unique prefix'
else:
return a[0]
def test():
print getchoice('Specify direction %s or <%s>: ',
("Left","Lexy","Right","Up","Down"), "Left")
test()
