Imagine that you are hired by the owner of ABC Hotel, to create a Python program for handling customer reservations. Specifically, a set of rooms has been reserved for extended stays until January 1, 2025. These include 10 single-bed rooms, 10 double-bed rooms, 5 executive rooms, and 2 presidential suites. These rooms at the hotel are allocated on a first-come, first-served basis. The owner aims to store customer information in the system, and the program should operate continuously once executed. The program will request the customer to indicate the commencement date of their stay, the checkout will be scheduled for January 1, 2025.

Original price for each type of room:

Single-bed room    – HK$1500/night

Double-bed room  – HK$2000/night

Executive room      – HK$5000/night

President Suite       – HK$10000/night

The hotel exclusively accommodates guests with a minimum stay requirement of 250 nights. For those meeting this criterion, the hotel extends the following discounts :

●   A 50% discount for stays ranging from 250 to 280 nights, inclusive.

●   A 60% discount for stays of 281 nights or more.

The following samples are coloured-coded, red color for user-input, blue color for output, orange color for new required skill, and black represents instructions/explanations.
