You've already had some advice so I'll just point out that a bare except

Try (groan!) catching StandardError instead.
There are some bare except:s in the stdlib, that adding another is
frowned on and removing one is smiled upon.
However:
>>> StandardError
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
StandardError
NameError: name 'StandardError' is not defined
Try:
>>> Exception
<class 'Exception'>
This catches everything except a few things like Keyboard Interrupt that
you normally should not catch.
>>> BaseException
<class 'BaseException'>
This catches everything, but signals that doing so is probably intentional.
