FAQ

Why required python version is equal or greater than 3.10?

• match .. case .. is introduced in 3.10 and I am not interested in supporting older releases

Why is it ugly?

• I am not an expert on Python
• It is not thread-safe
• I don't know what happens if two instances are created with the same name, and I don't care. I'd never do that
• The solo purpose is to have an easy to use and easy to read logger class

Why is it ugly but not that ugly?

• it is easy to use and easy to read
• I may keep this library up-to-date and even optimize it in the future
• at least it has a CI/CD pipeline

Installation

pip install uglylogger
