If you don’t know how to use it, I’ll give you an example

#! /usr/bin/env python

import sys
import logging

def add_log_file(infile=None):
    logger = logging.getLogger()
    if infile is not None:
        handler = logging.FileHandler(infile)
    else:
        handler = logging.StreamHandler()
    logger.handlers.append(handler)
    return

def main():
    for c in sys.argv[1:]:
        add_log_file(c)
    for c in sys.argv[1:]:
        logging.error('%s'%(c))


main()

The problem with filename is that you specify an absolute path and then try again, filemode="w". If you do this, a new file will be generated every time,

The environment under the interactive command line is different, especially for certain operations involving files and systems. For example, you can try creating a new process under the interactive command line.
