set __repr__ python code example

Example 1: __repr__ or __str__

very briefly
 - The default implementation is useless (it’s hard to think of one which wouldn’t be, but yeah)
 - __repr__ goal is to be unambiguous
 - __str__ goal is to be readable
 - Container’s __str__ uses contained objects’ __repr__

Example 2: python __repr__

class Person:
    name = ""
    age = 0

    def __init__(self, personName, personAge):
        self.name = personName
        self.age = personAge

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

    def __str__(self):
        return 'Person(name='+self.name+', age='+str(self.age)+ ')'
