- Logging Tutorial in Python | DON’T use Print for logging | How to Log messages in Python
In this video, we learn how to use logging in python. Python logging module can be used to log messages. We show why Print statement should not be used in Python for logging messages. And the advantages of using logging module over print statement in python.
This logging tutorial video also covers the different levels of logging in python. We look at DEBUG, INFO, WARNING, ERROR, CRITICAL levels of logging in python. We explain these logging levels by writing programs and showcasing the difference in logging by setting different logging levels.
If you are new to programming, then you might consider using print statement for logging messages in Python and you may wonder why use python logging module when print can do the same things but, in this video, I give you 2 use cases of the advantages of using logging module over print in python for the purpose of logging messages.
In the beginning of this python tutorial video, we discuss how to use logging module to log messages to your console and then we also see how to log messages to a file.
We also cover how to disable logging in python.
We start by using the root logger which is the default logger when we use the basic configuration of logging in python. At the end of the video, we also show to create your own logger and how to create separate logger for each of your program.
We discuss why it is not recommended to use root logger and the problems of using root logger. We look at the syntax to create a unique logger for each of our program.
Python Website to get the different logging format:

THANK YOU,
Thoufiq
Thanks for the useful lesson! Only you could explain it so clearly out of any CZcams video I have ever seen
Couldn't have been explained better. Thank You very much!
Amazing explanation! I have recently started using logging and your video gave me a wholesome understanding of it! I was facing the same issue with the root logger which you have explained nicely at the end. :) Thank you so much!
Excellent video. I was struggling to understand , you made it clear. Thanks a lot. New subscriber
We can learn rocket science also if you teach like this ....salute to you man
Just a splendid explanation ! Thanks
Excellent - beautifully explained with an example rather than jumping straight into the 5 levels of logging as most videos do
Thank you.. Glad it helped
awesome method of explain, just loved the style of teach, only felt near logger some confusion,
Thank you very much for the video? I come to know that there is logging method debug❤
EXCELLENT VIDEO!!!
Thanks so much for this video! I was struggling with my first program to use logging.
I kept using the default (root) logging...your video showed me to built my own logger.
I needed to change the fileHandler on the fly, this wasn't covered in the video, but I was able to figure out how to remove the previous fileHandler and add a new one with the new (different) file.
I wasted way too much time (days) reading stackoverflow for answers...After a couple of hours looking for a video tutorial, I stumbled across your video.
THANKS TONS!
Thank you so very much!
So glad this helped you.
It’s feedback like these that motivates a creator to keep going ❤️🙏
That was very clear!
Well there goes one of my bad habits. Don't know if I skipped over the section, but none of the python tutorials I watched spoke about logging, even in the debug sections. Thank you for enlightening me
glad you like this one :)
Your dedication to make valuable, fantastic, excellent and informative content... is simply commendable. Keep up the GOLD standards👌👌👌
❤️thank you 😍
How can I copy the generated log to different directory ? By default the logs are generated in same directory from were the script is run.

You didn't show a method how to let external log file in .txt or other format. How to send management my report of which test cases passed which failed? Thanks
Hi #techFTQ,,suppose my date is 23/10/2023 -25/10/2023.I want to have 1 print statement based on everyday..
Can you have that without scheduler
Beautifully explained

Glad this helped
Best explanation 🔥
Thank you :)
Very useful!
Thank you Sudarshan 🙏🏼
Really easy to understand. I wonder why this tut is not as popular as others. BTW, can you upload your code next time so we don't have to type them again T.T
Thanks Minh Dang 🙏🏼
So glad you liked it ..
Yes from the past few videos, I have started posting all the scripts in my blog.. will continue to do so..
Brilliant. How about if we want to output the log messages from several modules to the console, rather than to log files? Can that be done?
Thanks
Thank you 🙏🏼
If you do not mention the filename argument in the logging.basicConfig then log msges would be directly printed on your console..
With that much logging code now we need to debug the logger with print statements
Haha really funny 😄
Thank you🙏
You’re welcome 😊
As a beginner, it's very very important. Previously I used to use print() 😂😂😂. Now I realized how dump I was.
How to filter unwanted data ?from a log file? What should I learn to know about this ?do u have any knowledge sir?
Valuable content :)
Thanks again Sudheesh 🙏🏼
@@techTFQ Please make videos on OOPS concept
Will plan it for a future video Sudheesh ..

Don't you really want the log messages coming from the called script(savetoFile.py) to go to the log file (employee.log) specified for the calling script(employee.py). Imagine savetoFile.py is a common library function called used by various other scripts.
WARNING: Do not use logging to replace common messages on your system! Use print instead. You will be flooded with unwanted messages from third-party packages! The use of logging in these cases is considered bad practice!
