Which method would you override to change the string representation of a custom object? __str____repr____string____reprstr__

To change the string representation of a custom object in Python, you would override the __str__ or __repr__ method.

Here's how you can do it:

1. Define your class. For example, let's create a class named Person.

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

2. Override the __str__ method. This method should return a string, and it will be called when you use the str() function on an instance of your class, or when you try to print the instance.

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

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

3. Similarly, you can override the __repr__ method. This method is used to return a string that represents a printable version of the object. It's called by built-in function repr(), and by backticks in earlier versions of Python.

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

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

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

Note: If you only implement one of these methods, Python will use it as a fallback for the other if needed. If possible, __repr__ should return a string that reproduces the exact object when fed to eval().
