Objectives:
- Practice using single dimensional lists
- Practice using two dimensional lists
Description:
For this project, you get to write a Python script that will simulate a one-sided version of the game
Battleship. Battleship has five different kinds of ships:
| Name |
Number of hits |
| Battleship | 4 |
| Carrier | 5 |
| Destroyer | 3 |
| Frigate | 2 |
| Submarine | 3 |
| Tender | 2 |
Your script needs to request the name of a file with the location of each ship.
The format of this input file is as follows: (each item is separate by a TAB-character)
shipName startRowIndex startColIndex endRowIndex endColIndex
...
You can assume that all six ships will be specified in a file and that they will start at the indicated coordinate and end AT the specified coordinate.
Track the location of all of the ships using a two dimensional
list (the "ocean").
When displaying the "ocean", use just the first letter of each ship.
For example, given the locations file
project7-input-shipLocationsA.tab:
Battleship 0 0 0 3
Carrier 0 9 4 9
Destroyer 9 7 9 9
Frigate 8 0 9 0
Submarine 2 2 2 4
Tender 2 7 3 7
your script should display the "ocean" as follows:
0123456789
0 BBBB C
1 C
2 SSS T C
3 T C
4 C
5
6
7
8 F
9 F DDD
Additionally, your script should request the user to also input the name of a file with the shots for a single player.
Each shot is recorded on it's own line by specifying the row and column of the shot: (each item is separate by a TAB-character)
rowIndex colIndex
...
Your script needs to display the "ocean" after accounting for each shot.
If the shot hit a ship, indicate this by using a lowercase letter for the ship at that location.
If the shot sunk a ship, display that information as well.
Additionally, you need to use a
main() function and at least one single dimensional
list.

Submission
Submit your python script and rubric using the
handin program. For
handin, for this project, type the following in a terminal window exactly as it appears:
handin project7 project7.py rubric7.txt
To verify your submission, type the following in a terminal window:
handin project7
Rubric:
Points Item
---------- --------------------------------------------------------------
_____ / 13 Meaniful comments (at the beginning of the file, before each function, etc.)
_____ / 15 General good programming practice:
+ Properly handles input file (e.g., handles IO exceptions, close the file)
+ main() function
+ Single and two-dimensional lists (specific to this project)
_____ / 15 Accurately displays the ocean
_____ / 35 Accurately executes the commands in the shots file
_____ / 2 Completed rubric (estimates for each line including hours spent)
_____ / 80 Total
_____ Approximate number of hours spent
Helps
- Before writing any code, write the comments first!
- Write the code iteratively. For example, write the code to get the ships stored to their respective positions on the "ocean". ...
Notes
- Optionally, you can replace typing from the keyboard with the contents of a file. For example, try on ranger:
(echo "project7-input-shipLocationsA.tab"; echo "project7-input-shotsA.tab" ) | python3 project7.py
