magic methods, do we need them ?

i assume python uses these dunder methods internally and i hope we generally don't use them in our code. is this for understanding how python works in the background or do we need them in our code ?

Good question! It is important to understand how python executes through the use of magic methods. In general, you won't need to create magic methods unless you are extending a build-in class to alter its standard behavior.

One magic method you use almost every time you create a new class is __init__. Another magic method __cmp__ might be needed if the class you are creating needs to be compared to other instances of this class.
