__init__ is called to set up a new instance of an object, whenever one is created. For example:

class Something():
    def __init__(self, newValue):
        self.value = newValue

newObject = Something("here's some text")
newObject.value
>>> "here's some text"

To explain, we've defined a new class called Something, and we've written an initializer for it that takes in some data and sets it to a property called value on the new instance. After that, we've created a new instance of Something and given it a string "here's some text", and we've assigned that new Something instance to a variable called newObject. When we read what data is in newObject.value, we can see that it's the string "here's some text" like we passed into Something's initializer
