Hi! First I want to note that this task would be easier and better to do
with a break statement, so it's quite unfortunate that the teacher did
not cover the right tools (and very basic ones, in fact) and yet given
this task.
Another question: are you allowed to use functions? (I'm guessing not).
You can do this task much easier if you write it out in pseudo code
before you go to python code. For example, to convert your existing
code to pseudo code:
* set floor_number to 0
* get number of floors from the user
* as long as number of floors is less than 1:
* print invalid input
* get number of floors from the user
* as long as number of floors is more than 1:
* increment floor_number
* get number of rooms
* as long as number of rooms is less than 10:
* get number of rooms
* get occupied_rooms
* occupancy_rate = occupied rooms / number of rooms
* how do we keep track of total rooms and total occupied rooms here??
Does it make it easier to think about the logic of the program?
