Write a simple property

• Write a simple Promo class. Its constructor receives two variables: name (which must be a string) and expires (which must be a datetime object).

• Add a property called expired which returns a boolean value indicating whether the promo has expired or not.

Proposed solution

from datetime import datetime, timedelta

NOW = datetime.now()


class Promo:
    def __init__(self, name, expires):
        self.name = str(name)
        self.expires = expires
    
    @property    
    def expired(self):
        if self.expires < NOW:
            return True
        return False

Unit Testing

Write tests for:

• Check output with promo expired
• Check output with promo not expired
• Check if property is used in the Promo class
