Parking_Lot.py

"""You are tasked with designing a parking lot management system for a multi-level parking structure. 
The parking structure has multiple levels, each containing a certain number of parking spots. 
The parking spots can be either regular spots or spots reserved for specific vehicles (e.g., handicapped spots).

Design a data structure and implement the necessary functions to support the parking lot management system.
The data structure should store information about the parking levels, spots, and their availability. 
Additionally, the functions should include the ability to check spot availability, park vehicles, and retrieve parking details.

Write a class ParkingLot that represents the parking lot management system. The class should include the following methods:

add_level(level_number, num_regular_spots, num_reserved_spots): Adds a new parking level with the specified level number, 
number of regular spots, and number of reserved spots.

park_vehicle(vehicle_number, is_reserved): Parks a vehicle with the specified vehicle number in an available spot.
      If the vehicle is reserved, it should be parked in a reserved spot if available; otherwise, it should be parked in a regular spot.

unpark_vehicle(vehicle_number): Unparks the vehicle with the specified vehicle number from the parking lot.

get_parking_details(): Returns the current parking details, including the occupied and available spots on each level.

You can assume that vehicle numbers are unique within the parking lot.
Implement the ParkingLot class with the above methods, along with any additional helper methods or data structures you may need.

Note: You do not need to handle edge cases such as input validation or error handling in this implementation."""
