Cannot Import GTK in Ubuntu Python 2.7

I'm trying to import GTK in Ubuntu Python 2.7, and I get the following error. PyGTK imports just fine. When I import gtk, I get the following error:

Exception in Tkinter callback Traceback (most recent call last):

    lineno, file=file, line=line))
TypeError: idle_formatwarning() got an unexpected keyword argument 'file'

How do I fix this?

This is a bug in idle. Looking at the last line of that error message:

File "/usr/lib/python2.7/idlelib/PyShell.py", line 64, in idle_showwarning
    lineno, file=file, line=line))
TypeError: idle_formatwarning() got an unexpected keyword argument 'file'

This is saying that the warning.idle_showwarning method does not have an argument "file".

Sure enough looking at /usr/lib/python2.7/warnings.py

def formatwarning(message, category, filename, lineno, line=None)

There is no such argument.

This apparently has been resolved in source control but I do not think it has made it into a release yet. I would just hack the /usr/lib/python2.7/idlelib/PyShell.py file and remove the offending argument from line 64.

Then try it again...

Try it outside of IDLE. The error here is in IDLE, not your code.

Create a new script that contains import gtk and save it anywhere.

From the command line, in the directory where your script is located, run python whatever_your_scripts_name_is.py.

See if you get an error. You may not be able to import gtk in IDLE.

Edit: There is apparently a problem with GTK and IDLE in some situations on Ubuntu.

Try a different Python shell; I'd recommend IPython which you can install with Synaptic or sudo apt-get install ipython.
