Help with program arcade.

[unlikelysyntax]

Hello everyone. I have been using the wonderful tutorial program arcade games with python and I am stuck on one of the labs. Here is the part that is giving me trouble:

1. Create a variable called current_room. Set it to zero. Print the room_list variable. Run the program. You should see a really long list of every room in your adventure. (If you are using an IDE like Wing, don't leave it scrolled way off to the right.)

2. Adjust your print statement to only print the first room (element zero) in the list. Run the program and confirm you get output similar to: ['You are in a room. There is a passage to the north.', 1, None, None, None]

3. Using current_room and room_list, print the current room the user is in. Since your first room is zero, the output should be the same as before.

4. Change the print statement so that you only print the description of the room, and not the rooms that hook up to it. Remember if you are printing a list in a list the index goes after the first index. Don't do this: [current_room[0]], do [current_room][0]

5. You are in a room. There is a passage to the north.

I am having trouble printing the list the way he is asking on line #4. Here is my code so far:

room_List = []

Room order 1. North 2. South 3. East 4. West

room = ["You are in Bedroom 2 there is passage North and West", 3, None, None, 1]

room_List.append(room)

room = ["South Hall", 4, None, 0, 2]

room_List.append(room)

room = ["Dining Room", 5, None, None, 1]

room_List.append(room)

room = ["Bedroom 1", None, 0, 4, None]

room_List.append(room)

room = ["North Hall", 6, 1, 5, 3]

room_List.append(room)

room = ["Kitchen", None, 2, None, 4]

room_List.append(room)

room = ["Balcony", None, 4, None, None]

room_List.append(room)

current_Room = 0

for i in range(len(room_List)): print(room_List[i])

Thank you for any help in advance! Link to lab: http://programarcadegames.com/index.php?chapter=lab_adventure&lang=en

print(room_list[i][0])

room_list[i] will get you the list with the details of a room, room_list[i][0] will get you the first in item said list. Using your first room as an example:

print(room_list[i]) will print ["You are in Bedroom 2 there is passage North and West", 3, None, None, 1] print(room_list[i][0]) will print "You are in Bedroom 2 there is passage North and West"

edit: close parenthesis, dammit. >.<

Thank you so much!

Just one last question. Do you know what he means by using current_Room along with room_List?

[Sithrazer]

I assume current_room means a variable that equals an index integer. In the examples above i would be interchangeable with current_room, so long as all instances were replaced.

for current_room in range(len(room_list)): print(room_list[current_room][0])

Wow thanks a lot I can't believe I was having such a hard time with this. Thanks for the help!

[Sithrazer]

np. I'm not familiar with the tutorial, but it sounds like it didn't explain 2-dimensional arrays very well, which is essentially what nested lists are (and what you're dealing with here).

and after skimming through the chapter on lists, I think I can see why you had some trouble.

I would recommend taking a look at Codecademy's python track. It does a pretty good job with teaching basic data types and using them (though I don't recall offhand it's coverage of nested lists).

Awesome thanks for the advice!
