I am having some problems with magic methods in Python. They are defined inside a class using built-in functions and are not directly callable. What are some helpful resources with this topic? Thanks.

Here's my beginner-friendly article on magic methods: https://conceptcoaster.com/course/python-tutorial/magic-meth...

If you have any trouble understanding it, go to the homepage: https://conceptcoaster.com/course/python-tutorial/ and work your way to magic methods.

Word to the wise: avoid anything "magic" when writing code.

Word to the wise. Better to stay silent and for people to think you stupid than to open your mouth and have them know for sure.

Python magic methods are not "magic" but are a very standard part of the language and are well documented.
