On top of what Ahri suggested, they *also* might be used in class definition. You for example always define the __init__ magic method. Apart from defining the class's features, you may for example tell it to increment a counter each time an object is instantiated. So you can keep track of how many of such objects were created already.

But really vast applications of this - you usually define __str__ or __repr__ which define how the print(object_name) should behave. You can overload standard operators, customize attribute access and many more.
