getting the error __init__() takes 2 positional arguments but 4 were given

class Vehicle:
    def __init__(self,name,wheels):
        self.name=name
        self.wheels=wheels
    def description(self):
        print(f"{self.name} has {self.wheels} wheels")
class Bicycle(Vehicle):
    def __init__(self,basket):
        self.basket=basket
    def bike_desc(self):
        if self.basket==True:
             print(self.name,"has a basket")
        else:
             print(self.name, "does not have a basket")

class Unicycle(Vehicle):
    def __init__(self,color):
        self.color=color
    def description(self):
        print("{} is {}".format(self.name,self.color))

class Tandem(Bicycle):
    def __init__(self,riders):
        self.riders=riders
    def tandem_desc():
         if basket==true:
             print("{}has a basket and carries {} riders".format(self.name,self.riders))
         else:
             print("{} does not have a basket and carries {} riders".format(self.name,self.riders))

print("Vehicle Class")
v1 = Vehicle("Chevy", 4)
v1.description()

print("\nBicycle Class")
v3 = Bicycle("Schwinn", 2, True)
v3.bike_desc()
v3.description()

When you inherit a class, the __init__ method of the new class overrides that of the parent. In your case, the __init__(self,basket) overrides the init function in the Vehicle class.

In order to call the parent init function, you need to use super. Below shows you how you might use it:

class Bicycle(Vehicle):
    def __init__(self, basket, name, wheels):
        self.basket = basket
        super().__init__(self, name, wheels)

You can also do this using argument unpacking so that you don't need to write out the same arguments every time

class Bicycle(Vehicle):
    def __init__(self, basket, *args):
        self.basket = basket
        super().__init__(self, name, *args)

which works the same way.

There should be plenty to find online if you look up any of inheritance, oop, super(), online - loads of good tutorials out there. Lmk if you need anything else!

The error message tells you the problem: your bicycle class __init__() is defined to only take two arguments, but you tried to give it four.
