Here's your program with some extra comments to get you started:

    #This program will calculate the occupancy rate of a hotel
    floor_number = 0


    number_of_floors = int(input("How many floors are in the hotel?: "))
    while number_of_floors < 1:
        print ("Invalid input!")

        number_of_floors = input("Enter the number of floors in the hotel: ")
            # Remember you need to make sure this is an int, just like before.
            # number_of_floors = int(input("Enter the number of floors
in the hotel: ")) Right now it's a string.


    while number_of_floors > 1:
        # This loop runs forever, as number_of_floors never changes. You need
        # to do something to `number_of_floors` such as de-increment it e.g:
        # `number_of_floors -= 1`, that way we will *eventually* have
        # number_of_floors less than 1, thus stopping the loop. A better
        # idea would be to use a `for` loop instead of the above `while`
        # loop. For example::
        #
        #   for i in range(number_of_floors):
        #       # blah... do something for each floor. This loop
auto-terminates.
        #

        floor_number = floor_number + 1
        print()
        print ("For floor #",floor_number)
        rooms_on_floor = int(input("How many rooms are on the floor ?: " ))

        while rooms_on_floor < 10:
            print ("Invalid input!")
                # You might consider telling your user why their input is
                # invalid. e.g: "rooms on floor must be greater than 10".

            rooms_on_floor = int(input("Enter the number of rooms on floor: "))


        occupied_rooms = int(input("How many rooms on the floor are
occupied?: "))

        #CALCULATE OCCUPANCY RATE FOR FLOOR
        occupancy_rate = occupied_rooms / rooms_on_floor
        print ("The occupancy rate for this floor is ",occupancy_rate)
