Unexpected python behaviour

[Richard Philips]

Consider the script:

def test(drivers={}):
    if drivers:
        print drivers
    else:
        drivers["A"] = "B"

if __name__  == "__main__":
    test()
    test()

prints in stdout:
{'A': 'B'}

I expected that nothing would be displayed.
I do not understand this behaviour (python2.3 on WinXP and Linux).

If anybody can explain this situation, you are welcome.

Thank you.
