Fuzzyman is right.

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
