try import except want lineno from Exception

I am importing module files, and want to catch an error (if any) and
print the filename and line number of the error.
The "Exception ,e" does not return, or does not have the attirbutes listed 
above. It only returns e="line() takes exactly 2 arguments (3 given)"

I think I want to use SyntaxError as it has the attributes: filename, 
lineno, offset and text.
I have found no info on traceback.
With the code below, how do I find the **line_number**?
Thanks.
