What does the __str__() method do in a Python class?

The __str__() method in a Python class returns a string representation of the object. This method is called when you print an object or convert it to a string using str(). It is intended to provide a readable and informative representation of the object, suitable for end-users.

class Car:
    def __init__(self, make, model):
        self.make = make
        self.model = model

    def __str__(self):
        return f"{self.make} {self.model}"

# Creating an object of Car class
my_car = Car("Toyota", "Corolla")
print(my_car)  # Output: Toyota Corolla

In this example, the __str__() method is used to return a string that represents the Car object in a readable format. When you print the object, the output is the string returned by __str__().

Defining the __str__() method in your classes is important for making your objects more user-friendly and easier to understand when displayed or logged.
