Here's how to do what you describe:

import sys
try:
    raise ValueError, "Foo"
except:
    tb = sys.exc_info()[2]
    print tb.tb_frame.f_lineno
    print tb.tb_frame.f_code.co_filename

This will give you the file name and line number. If you want the actual text
of the line, you can simply read the information from the file. 


Cheers,



Aldo
