[Tutor] While loops

[myles broomes]

I am currently coding a 'text-based adventure game', and im having a bit of trouble with while loops. Here is my code so far: #Text-based Adventure RPG
#The player travels through different towns and dungeons
#The overall goal of the game is simple; the player must make it to the final town,
#Battling various monsters and overcoming several challenges along the wayimport timeplayer_name = None

                elif plyr_location=='Left Embark Town':
                        return #Launch the game
main()
 
 For some reason that I cant figure out, the 'Player creation loop' wont run when I try to run the program. When I try to run it in IDLE, nothing happens, Any help is much appreciated. Myles Broomes
