Thanks for the response GL.
What I am looking for is a module to wrap raw_input so it can handle
some of the validation.
e.g.)
response = display_prompt( question, valid_responses,
default_response )
or similar. valid_responses could be a tuple of regexp strings that
would compare against a raw_input and return one in the list. Ideally
I could customize the error message (for responses not in
valid_response), etc.
I know it isn't rocket science to write it and I have something
already in place. I'd rather use a module built for the purpose now
that I have several scripts that will use the functionality.
Thanks!
James.
FYI: This is what I have so far:
from re import compile
def yes_no(question, default=None):
"""Prompt the user with a yes or no question."""
if default == "y":
question = "".join((question, " [Y/n]: "))
elif default == "n":
question = "".join((question, " [y/N]: "))
else:
question = "".join((question, " [y/n]: "))
valid_answer = "[yn]"
invalid_message = "Answer must be y or n"
answer = prompt(question, valid_answer, invalid_message, default)
return answer == 'y'
def prompt(question, valid_answer, invalid_message, default=None):
"""Prompt the user with a question and validate their response."""
is_valid = False;
compiled_valid_answers = compile(valid_answer)
while not is_valid:
answer = raw_input(question).lower()
if answer == "" and default is not None:
answer = default
is_valid = compiled_valid_answers.match(answer)
if not is_valid:
print invalid_message
return answer
