Open Hours Checker

open_hours.py

"""
Edge cases:
1. Empty hours hours = {}
2. Some days not having open/close hours or both {"close":{"day":0,"time":""},"open":{"day":0,"time":""}},
3. Some stores might not have hours.
4. Some stores might have close hours and not open hours. 

example:
isOpen('store_1') // open
isOpen('store_2') // closed
isOpen('store_3') // closed
isOpen('store_4') // open
getOpenStores() // ['store_1', 'store_4']
