# When To Use __repr__ vs __str__?
# Emulate what the std lib does:

import datetime
today = datetime.date.today()

# Result of __str__ should be readable:

print(str(today))

# Output
# '2017-02-02'

# Result of __repr__ should be unambiguous:

print(repr(today))

# Output
# 'datetime.date(2017, 2, 2)'

# Python interpreter sessions use 
# __repr__ to inspect objects:

print(today)

# Output
# datetime.date(2017, 2, 2)

class Person:

    def __init__(self, person_name, person_age):
        self.name = person_name
        self.age = person_age

    def __str__(self):
        return f'Person name is {self.name} and age is {self.age}'

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


p = Person('Pankaj', 34)

print(p.__str__())
print(p.__repr__())
Output:

Person name is Pankaj and age is 34
Person(name=Pankaj, age=34)
