What is __repr__?Instance method that returns an “official” string representation of an instanceInstance method that prints an “official” string representation of an instanceInstance method that returns the dictionary representation of an instance

The __repr__ is an instance method in Python that returns a string representing a printable version of an object. This method is used to output the "official" representation of the object, which can be used to reproduce the object using the eval() function. It's often used for debugging and logging. It's different from __str__, which is used to find the "informal" or nicely printable string representation of an object.

Here is an example:

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __repr__(self):
        return f'Person(name={self.name}, age={self.age})'

p = Person('John', 30)
print(p)  # Outputs: Person(name=John, age=30)

In this example, the __repr__ method returns a string that looks like the code you would need to write to create the Person object. If you print the Person object p, Python calls p.__repr__() to determine what to print.
