Duplicate output on Python tab completion (OsX 10.8) -

using snippet below, have added tab completion python interpreter.

import readline import rlcompleter if 'libedit' in readline.__doc__:     readline.parse_and_bind("bind ^i rl_complete") else:     readline.parse_and_bind("tab: complete") 

however, have encountered weird behaviour after hitting tab, interpreter give duplicates such:

108 possibilities! min 2, max 4 duplicates.

furthermore,

• if subclass dict total number of possibilities increases 160 (and 209, 258).
• if type enough characters tab nail command, without displaying duplicates.

any pointers or debugging tips appreciated.

i have solved issue adding custom completer. works expected.

import readline import rlcompleter  c = rlcompleter.completer()  def complete(text, state):     buffer = readline.get_line_buffer()     first = c.complete(buffer, 0)     if state == 0:         return first     current = c.complete(buffer, state)     if current != first:         return current  readline.parse_and_bind('bind ^i rl_complete') readline.set_completer(complete)
