Python in a Nutshell

expect

Synopsis

                     t.expect(res,timeout=None)

Reads data from the connection until it matches any of the regular expressions that are the items of list res, or until timeout seconds elapse when timeout is not None. Regular expressions and match objects are covered in Chapter 9. Returns a tuple of three items ( i,mo,txt ), where i is the index in res of the regular expression that matched, mo is the match object, and txt is all the text read until the match, included. Raises EOFError when the connection is closed and no data is available; otherwise, when it gets no match, returns (-1,None,txt ), where txt is all the text read, or possibly '' if nothing was read before a timeout. Results are non-deterministic if more than one item in res can match, or if any of the items in res include greedy parts (such as '.*').
