This is because the function is done once it detects the y or n, so
after you enter the n, one of those if/else statements has fired, and
the function has nothing else to do. You will want a while loop,
something like:
repeat=True
while repeat:
answer=raw_input("Is the data okay?")
if answer=="y": repeat=False
else:
promptInput()
repeat=True
Anyway, something along those lines. Look in the manual for while
loops. Basically, they are a way to repeat an action until a condition
is met. You will also run across for loops, which are mostly used for
repeating an event a set number of times. You can use them
interchangeably, but they each have situations where one works better
than the other, and you want a while loop here.
