Here is what i want to do. I have a question in my program, and i want
to do tab completion for the valid answers.
Say i have :
--snip--
validanswers = [ 'yes', 'no', 'maybe', 'tuesday', 'never' ]
#and i ask
sys.stdout.write("Answer the Question: ")
answer = sys.stdin.readline().rstrip()
if answer not in valid answers:
print "Wrong!"
--snip--
But what i want is when i enter the answer i can hit tab and it'll
complete one of the validanswers
I know i can do tab complete with readline and 'raw_input('')' but
that's only to execute python commands right?

On a gui on this would be a little bit easier but it's a completley
diffrent realm when doing it in the console. It makes it a little more
difficult when using stdin.readline() because you can only read line by
line. Here is my implmentation.
import sys
validanswers = [ 'yes', 'no', 'maybe', 'tuesday', 'never' ]
while True:
sys.stdout.write("Answer the Question: ")
answer = sys.stdin.readline().rstrip()
for valid in validanswers:
if valid.startswith(answer.strip("\t")):
answer = valid
else:
print "Invalid Answer: Please enter a valid answer"
continue
break
print "You have answered, ", answer
I'm at school and wasn't able to test it, but it looks like it should
work.

Not sure what your trying to do, but it doesn't work. :)
valid doesn't exsist, and if you make vaid =
sys.stdin.readline().rstrip(), then answer doesn't exsist.
Either way, it doesn't take the tab tell after you hit enter, Not
really what i was getting at. What i want is like a bash shell prompt.
>From a bash shell prompt try ls <TAB<TAB>, like that. (readline does
that for bash, but i don't know how to get readline to do anything but
python commands in python).

I think you may "play" width curses library: readline() read... while you
input a "newline", but you need to catch single keys (the "TAB" key,
foremost)

valid doesn't exsist
it's assigned to by the for-in loop, and is only used inside it.

you can use the "readline" module with a custom completer class. see
the second example on this page: http://effbot.org/librarybook/readline.htm

#Thanks for the link from Fredrik Lundh
#from http://effbot.org/librarybook/readline.htm
#You do it like this,
class Completer:
def __init__(self, words):
self.words = words
self.prefix = None
def complete(self, prefix, index):
if prefix != self.prefix:
self.matching_words = [
w for w in self.words if w.startswith(prefix)
]
self.prefix = prefix
try:
return self.matching_words[index]
except IndexError:
return None
import readline
# a set of more or less interesting words
validanswers = [ 'yes', 'no', 'maybe', 'tuesday', 'never' ]
completer = Completer(validanswers)
readline.parse_and_bind("tab: complete")
readline.set_completer(completer.complete)
# try it out!
while 1:
answer = raw_input("Answer the Question: ")
if answer not in validanswers:
print "Wrong!"
else:
print "Your answer is",answer
