Fuzzyman is right.

In your formulation the comma binds more tightly than the as keyword. In import statements it's the other way around. That seems like it might be a source of confusion.

Perhaps parentheses around the exception list should be mandatory for the 2-or-more exceptions case?

except NameError as e: --> fine except (NameError) as e: --> fine except (NameError,) as e: --> fine

except NameError, OtherError as e: --> SyntaxError except (NameError, OtherError) as e: --> fine
