Solution
The __str__ is an instance method in Python that returns an "informal" and nicely printable string representation of an instance. It is one of Python's 'dunder' methods, and it's used for string representation of an instance. While implementing __str__, we should remember that it must return a string. If it doesn't, Python raises a TypeError exception.
Here is an example of how it can be used:
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})'
p = Person('John', 30)
print(p) # Outputs: Person(name=John, age=30)
In this example, the __str__ method returns a string that looks like the valid Python expression which could be used to recreate an object with the same value (given an appropriate environment). When we print the object, Python invokes the __str__ method, and it prints the string it returned.
