Reporting the line number of an exception

[sophie_newbie]

I'm sure this is exceedingly simple but I can't find it anywhere. When
I catch an exception I would like to report the line number of the
exception as well as the error info.

try:
    someError()
except Exception, e:
    "print_error_and_line_number"

How do I find the line number?

Thanks for any help!
