"TypeError: Person() takes 1 positional argument but 2 were given" but the constructor takes two arguments

Question

This is the strangest thing. My python has just stopped handling classes with multiple parameters in their ctors? Running python 3.8.10 getting error TypeError: Person() takes 1 positional argument but 2 were given

def Person(object):
    def __init__(self, a, b):
        self.aa = a
        self.bb = b

pp = Person(20, 40)

If I bring the Person __init__ down to one parameter, then it works. If I raise it to 3, then I get the same takes 1 but 3 were given error. I’m totally stumped?

Answer 1

You’ve declared your Person class wrong. You used def instead of class, meaning that you actually have a function called Person with a local function called __init__.

Try this:

class Person(object):
    def __init__(self, a, b):
        self.aa = a
        self.bb = b
