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

import inspect
import traceback

def method():
   frame = inspect.currentframe()
   stack_trace = traceback.format_stack(frame)
   print ''.join(stack_trace)

Use stack_trace[:-1] to avoid including method/printinfo in the stack trace.

Current function name, module and line number you can do simply by changing your format string to include them.

logging.basicConfig(
    filename = fileName,
    format = "%(levelname) -10s %(asctime)s %(module)s:%(lineno)s %(funcName)s %(message)s",
    level = logging.DEBUG
)

Most people only want the stack when logging an exception, and the logging module does that automatically if you call logging.exception(). If you really want stack information at other times then you will need to use the traceback module for extract the additional information you need.
