python logging alternatives

Question

The Python logging module is cumbersome to use. Is there a more elegant alternative? Integration with desktop notifications would be a plus.

In what ways do you find the logging module to be cumbersome? What do you find lacking in its capabilities? — Nathan Davis, Oct 07 '10 at 03:33
@NathanDavis well just to get started you need to write about 6 lines... want to add to stdout too - thats about another 4, if you can get it to work. — dreab, Jun 30 '20 at 08:09
Anyways, for people who are here, just like me, structlog, loguru are two good alternatives — rawwar, Jul 27 '22 at 03:06
@InAFlash isn't it weird that there is a library for everything in python BUT logging LOL. There's no single decent one. However, structlog looks quite promissing. — t3chb0t, Aug 03 '22 at 09:30
i mean, why to worry when print("-----> I'm here <-------") works ? — rawwar, Aug 03 '22 at 09:32
@InAFlash it sure does... but not so much if you want to send the logs into a database to let another app analze them and send alarms. — t3chb0t, Aug 03 '22 at 09:46

You can look into Twiggy, it's an early stage attempt to build a more pythonic alternative to the logging module.

seems dead... last commit was over a year ago – tshepang Jul 18 '12 at 21:40

Not dead, but moved. The documentation is at https://twiggy.readthedocs.org and the development is on Github at https://github.com/wearpants/twiggy/ – Ian E Aug 06 '13 at 00:09
As of today it seems not to be available for Python 3.x - and also not in a proper state for 2.x, the github readme says: "master is currently in flux and may be broken." – SHernandez May 10 '15 at 11:18
@SHernandez: I tried it today on 3.6 and it works fine. Not sure how robust this is but at least the example ran OK. – WoJ Feb 28 '19 at 21:06

Checkout logbook, it is much nicer to work with.

Logbook was mentioned in a comment but it deserves its own answer.

Tried it. It has the same problem as stdlib logging: The documentation is not good, in my opinion. And there are a lot less users, so no Google results for questions. I went back to stdlib logging, and found https://stackoverflow.com/questions/7507825/where-is-a-complete-example-of-logging-config-dictconfig most helpful. – Andreas Haferburg Feb 25 '20 at 13:55

You might want to have a look at pysimplelog. It's pure python, very simple to use, pip installable and provides what you need

from pysimplelog import Logger
L=Logger()
print L
>>> Logger (Version 0.2.1)
>>> log type  |log name  |level     |std flag  |file flag |
>>> ----------|----------|----------|----------|----------|
>>> debug     |DEBUG     |0.0       |True      |True      |
>>> info      |INFO      |10.0      |True      |True      |
>>> warn      |WARNING   |20.0      |True      |True      |
>>> error     |ERROR     |30.0      |True      |True      |
>>> critical  |CRITICAL  |100.0     |True      |True      |

L.info('I am an info')
>>> 2016-09-26 15:01:17 - logger <INFO> I am an info

L.warn('I am a warning')
>>> 2016-09-26 15:01:17 - logger <WARNING> I am a warning

L.error('I am an error')
>>> 2016-09-26 15:01:17 - logger <ERROR> I am an error

and with those parameters, a 'simplelog.log' file will be created and updated automatically for you

+1 Hey that looks cool! One note however: I would not recommend using logging *outside of a function defintion* before it is known [whether that is safe](https://stackoverflow.com/questions/46356672/). — personal_cloud, Sep 23 '17 at 05:22

[31/10/2015 22:00:33] [DEBUG] [yourmodulename] [yourfunction_name():9] [PID:61314 TID:140735248744448] this is logger infomation from hello module

you can config logfile with console and file,I don't think desktop notication is a good idea,you can see the log information from console and logfiles
