How to save log file using Python?

Question

I have a powershell script and I save the log using this way

$Log = Start-Transcript -Path $Log_Path -Force

How do I use it in Python?

Is your file available on the system after having called your powershell ? — cocool97

You can write/save the log file using the below command.

logging.basicConfig(filename='path to the log file', level=...)

There is a filemode option to overwrite the file. To overwrite you can specifie filemode:w

logging.basicConfig(filename='logs.log',
            filemode='w',
            level=logging.INFO)

filemode: Specifies the mode to open the file, if filename is specified (if filemode is unspecified, it defaults to ‘a’).

this way I can save the log to file, but its not overwrite the log, how to make it overwrite?

Just add filemode:w to overwrite the file.

There is a logging module in python. You can import an use that.

import logging logging.basicConfig(level=logging.DEBUG) logging.debug('This will get logged')

And the output will be:

DEBUG:root:This will get logged

Similarly, you can use the other log levels too. You can find more about it here
