A function like pickRoom is hard to read with all the nested if statements. It can be made clearer with appropriate use of comments to explain what each section of the code is doing—checking the room, then checking the possible directions in the room. Add comments to pickRoom to make it easier to read.

Question

What will be an ideal response?

Answer 1

```
def pickRoom(direction , room):
#This code handles the command that quits the game
if (direction == "quit") or (direction == "exit"):
printNow("Goodbye!")
return "Exit"
#This section handles the help command which displays the introduction text again
if direction == "help":
showIntroduction()
return room
#The section below checks each room, then checks the possible directions in the room
#"Porch" room direction handling
if room == "Porch":
if direction == "north":
return "Entryway"
#"Entryway" room direction handling
if room == "Entryway":
if direction == "north":
return "Kitchen"
if direction == "east":
return "LivingRoom"
if direction == "south":
return "Porch"
#"Kitchen" room direction handling
if room == "Kitchen":
if direction == "east":
return "DiningRoom"
if direction == "south":
return "Entryway"
#"Livingroom" room direction handling
if room == "LivingRoom":
if direction == "west":
return "Entryway"
if direction == "north":
return "DiningRoom"
#"DiningRoom" room direction handling
if room == "DiningRoom":
if direction == "west":
return "Kitchen"
if direction == "south":
return "LivingRoom"

#This last section handles invalid commands
printNow("You can't (or don't want to) go in that direction.")
return room
```
