In this quiz, you'll test your understanding of Python's logging module. With this knowledge, you'll be able to add logging to your applications, which can help you debug errors and analyze performance.If you commonly use Python’s print() function to get information about the flow of you...
Most of the MSAL Python logs are already in debug level, which would be turned off by default. But if you want to enable debug logging to debug the OTHER modules in your Python script, therefore want to silence MSAL, you simply turn off the logger used by MSAL Python:logging.getLogger(...
