If the class constructor is declared in the following way: Which one of the assignments is invalid? class Class: def __init__(self, val=0): pass

class Class:
    def __init__(self, val=0):
        pass

• object = Class(1)
• object = Class()
• object = Class(None)
• object = Class(1, 2)

Explanation: An attempt to create an object of class Class using the assignment object = Class(1, 2) will raise a TypeError exception, because a maximum of two arguments are accepted by the __init__ declaration, not three arguments (self, 1, and 2).
