Intro Python level..l$\text{'}$m struggling to add windows to my code to match the 'After Result' picture. Keep it simple$-$just use imports already given. Add non$-$overlapping windows within the building borders. If possible, make windows randomly turn on$/$off one by one. Stars should move slowly in the background. Please comment changes with $\text{'}\backslash$# changed $\text{'}.$ Upload the output with Pycharm or any Python$|$compiler to prove it works well. Thanks!
