When I catch an exception, how do I get the type, file, and line number?


Catching an exception that would print like this:

Traceback (most recent call last):
  File "c:/tmp.py", line 1, in <module>
    4 / 0
ZeroDivisionError: integer division or modulo by zero

I want to format it into:

ZeroDivisonError, tmp.py, 1

Solution

  • import sys, os
    
    try:
        raise NotImplementedError("No error")
    except Exception as e:
        exc_type, exc_obj, exc_tb = sys.exc_info()
        fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
        print(exc_type, fname, exc_tb.tb_lineno)
