No behavior for arbitrary input autocomplete set-up

Hello there!

I am experiencing some problems with using pyreadline module for arbitrary input autcomplete. The summary of my problem is available here.

To sum up the problem, I am trying to implement an arbitrary autocomplete on windows for a command-line user interface I am writing. Inspired by the first answer to that StackOverflow question, I copied it and adapted to run with pyreadline instead of readline, since I am no windows.

from pyreadline import Readline

readline = Readline()

class MyCompleter(object):  # Custom completer

    def __init__(self, options):
        self.options = sorted(options)

    def complete(self, text, state):
        if state == 0:  # on first trigger, build possible matches
            if text:  # cache matches (entries that start with entered text)
                self.matches = [s for s in self.options
                                    if s and s.startswith(text)]
            else:  # no text entered, all matches possible
                self.matches = self.options[:]

        # return match indexed by state
        try:

            return self.matches[state]
        except IndexError:
            return None

completer = MyCompleter(["hello", "hi", "how are you", "goodbye", "great"])
readline.set_completer(completer.complete)
readline.parse_and_bind('tab: complete')

input = raw_input("Input: ")
print "You entered", input

The problem is however when I try to run that script, <TAB> does not lead to autocomplete, but instead appends a tab to the input.

I am trying to execute it on 2.7 Anaconda Python distribution in Windows 10, if this is of any use.
