Re: [Pydev-users] Python program running twice

[Fabio Z. <fa...@gm...>]

I don't think this is an issue in PyDev (I can't reproduce it and if
something as grave was happening, I'm pretty sure there'd be other reports
from it too).

My guess is that you're doing an os.walk() which walks recursively and it's
finding the name of the file more than once in a subdir and you're always
applying it to the local file later on (you can just print your 'f'
variable to know what it's finding).

Best Regards,

Fabio
