How can I log current line, and stack info with Python?

Question

I have logging function as follows.

logging.basicConfig(
    filename = fileName,
    format = \"%(levelname) -10s %(asctime)s %(message)s\",
    level = logging

Here is an example that i hope it can help you:

import inspect
import logging

logging.basicConfig(
    format = "%(levelname) -10s %(asctime)s %(message)s",
    level = logging.DEBUG
)

def test():

    caller_list = []
    frame = inspect.currentframe()
    this_frame = frame  # Save current frame.

    while frame.f_back:
        caller_list.append('{0}()'.format(frame.f_code.co_name))
        frame = frame.f_back

    caller_line = this_frame.f_back.f_lineno
    callers =  '/'.join(reversed(caller_list))

    logging.info('Line {0} : {1}'.format(caller_line, callers))

def foo():
    test()

def bar():
    foo()

bar()

Result:

INFO       2011-02-23 17:03:26,426 Line 28 : bar()/foo()/test()
