__str__ dunder method for OOP Python class still returns <__main__. object > instead of string

I am trying to define a class and have it return a properly formatted string. However, it returns the same <__main__.Card object at 0x7fb4439e4d00> result as when I print the class without the str dunder method. I assume that it has something to do with the fact that I pass no parameters into the class in the first place. Any explanation would be greatly appreciated, thank you.

class Card:

    def __init__(self):
        self.shape = "diamond"
        self.fill = random.choice(fill)
        self.number = random.choice(number)
        self.color = random.choice(color)

        def __str__(self):
            return f"{self.number}-{self.color}-{self.fill}-{self.shape}.png"

x = Card()
print(x)
print(x.__str__())
Solution

  • The indentation of __str__ method is wrong. Your code should be:

    class Card:
    def __init__(self):
        self.shape = "diamond"
        self.fill = random.choice(fill)
        self.number = random.choice(number)
        self.color = random.choice(color)

    def __str__(self):
        return f"{self.number}-{self.color}-{self.fill}-{self.shape}.png"


x = Card()
print(x)
print(str(x))
