Can I access sys.argv in python in interactive mode?

I'd like to do something like: 

% python foo bar
import sys
sys.argv

to get:

%  ['foo', 'bar']

but of course python dies when you enter an argument which is not a script or goes into non interactive mode if you do.

Can I do this somehow?

Run python this way:

python - foo bar

Then 

import sys
sys.argv

will work :)

Use - as script name:

python - foo bar

Test:

>>> import sys
>>> sys.argv
['-', 'foo', 'bar']

You could just set it manually for testing in IDLE:

try:
    __file__
except:
    sys.argv = [sys.argv[0], 'foo', 'bar']
