[Bug 1315733] [NEW] Python interactive interpreter does not indent with tabs, tries to tab-complete

[Erik B. Andersen]

Public bug reported:

Using the python3 interactive interpreter, I can not use tabs to indent
like I could on previous versions of Ubuntu (13.10 was what I was using
before, now I'm using 14.04).

When I try to indent on the python interpreter command line, it simply
does nothing the first time I press the tab key. The second time I press
it, it shows a bunch of autocomplete suggestions.

For example
>>> if (True):
... <tab>print("true!")
  File "<stdin>", line 2
    print("true!")
        ^
IndentationError: expected an indented block

Could this be related to http://bugs.python.org/issue18988? Is the fix
for that included in the version of python on 14.04?

I also found http://stackoverflow.com/questions/4809820/tab-key-not-
indenting-in-python, in which one of the comments to an answer suggests
trying <Ctrl-V><tab> when you want to insert a tab. That does work for
me:

>>> if (True):
... <Ctrl-V><tab>print("true")
... 
true
