A very simple module to extend the original rlcompleter module in standard library. After invoke python interpreter and import irlcompleter, you can indent and also complete valid python identifiers and keywords using a single "tab" key!
Note1: original python rlcompleter module only avail in unix-like environment Note2: if you seek a completer with history viewer support and more features you could try Sunjoong LEE's recipe at: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/496822

def complete(self, text, state):
if text == "":
#you could replace \t to 4 or 8 spaces if you prefer indent via spaces
return ['\t',None][state]
else:
return rlcompleter.Completer.complete(self,text,state)
#you could change this line to bind another key instead tab.

readline.set_completer(irlcompleter().complete)

Original rlcomplete module let python interpreter can complete valid python identifiers and keywords. But then you can't use tab key to indent, Using this module you could then press tab key to indent and also list possible keyword and indentifiers without using dir().
And if you import this module in your startup python script (which can set in $PYTHONSTARTUP environment variable), you can always get a indentable and auto-complete python!

suggestion.
Completer and history viewer support indent and file_match. I had extened your recipe. My recipe's url is http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/496822 .
Thanks the suggestions. I've edited my original recipe. :)
