Are you using a GUI or console?

How are you reading the characters in the first place?

if you can find a way to read characters from the keyboard
one at a time then

while True
     ch = getchar()
     if ch ==':'
        ch = getchar()
        if ch == 'q': break

Will work.

So the question becomers do you know how to write getchar()?
