<br>I have posted a log before, and add another template.<br><br>logging.Formatter('%(asctime)s - %(name)s - File "%(pathname)s", line %(lineno)d, in<%(funcName)s> - %(levelname)s - %(message)s', "%Y-%m-%d %H:%M:%S"), # A template that mimics traceback exceptions and can jump to the place where the log is printed<br><br><br>This template simulates the format of the traceback string, because the traceback string is supported by ides such as pycahrm as a jump, and the log template is made according to that format, then both the pycharm console and the log file can easily jump to the specified line of the specified file .<br><br><br>Install using pip:
pip install -i https://pypi.org/simple/ --upgrade multiprocessing_log_manager You don't need to specify the installation source, and the images of Ali and Douban update the official pypi package regularly.
<em id="__mceDel"><br>Template 3<br>The console log is like this, you can directly click on the link to automatically jump to the specified line of the specified file.<br><br>

Template 4, more friendly to pycahrm<br><br>

Using template 4, the linux system will be automatically recognized, because pycahrm has some unsightly background coloring, so use the above style on win<br><br>When the python program judges that it is running on the linux system, the log will automatically switch templates, the style is as follows<br><br>
