TypeError: __init__() got an unexpected keyword argument 'size'

This error occurs when you try to pass an unexpected keyword argument to a function or method.

For example, if you have a class called `Square` that has an `__init__` method that takes in a `width` and `height` argument, but you try to pass a `size` argument instead:

class Square:
    def __init__(self, width, height):
        self.width = width
        self.height = height

square = Square(size=10)

You will get the `TypeError: __init__() got an unexpected keyword argument 'size'` error because `__init__` does not expect a `size` argument.

To fix this error, you should either remove the unexpected keyword argument or modify the function or method to accept it. In the above example, you could modify the `__init__` method to accept a `size` argument:

class Square:
    def __init__(self, size):
        self.width = size
        self.height = size

square = Square(size=10)
