在python中的特定行上打印有序的dict信息

Question

The issue I currently have is that I want to print the value I have stored for my dict using a format that will make it easy for the player in my game to read. That way it is easy to interpret what is going on.

I have searched around for the last while and I cannot find a solution to what I want. I find things that are similar but do not preform what I need. I think i am searching the wrong terms as I am still wet behind the ears at programming.

pprint seems like it could solve the issue but the documentation is hard to decipher for me. I have also tried using for loops and while loops to achieve the effect I want but I cannot iterate though my dict correctly to illicit the needed effect.

import collections

def generateBoard():
    board = {(x,y):'W' for y in range(1,11) for x in range(1,11)}
    oboard = collections.OrderedDict(sorted(board.items()))
    return oboard

def printBoard(board):
    for x, y in board.items():
        return y

board1 = generateBoard()
printBoard(board1)

Currently all it will do is print out the 'W' over and over again like so.

'W'
'W'
'W'

I would like it to print out like this.

'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W'
'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W'
'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W' 'W'

Again, I have tried several different looping methods but I cannot figure out how to join the data together. Also because I order the dict it will print out the key:data in the order I want just not the format I want.

def printBoard(board):
    while True:
        z = 0
        while x <11:
            p = 0
            z + 1
            while p < 11:
                if board[x,y] == 'W':
                    print y.join(x)
                p + 1

This is one of the ways I tried and it failed miserably. It will not let me use an iterator for the if statement which I kinda knew about but I cannot think of a way to get it to go through the x, y tuple to print out the data in a nice format.

EDIT:

I went with tr33hous suggestion of using a class and grc 's example also. This code stores the values as I need them, and I can call the print function easily also. I also have it only taking the first character of what ever string I have entered in that position. This way later I can just concatenate damaged + ship-name and it will still print the board in a very concise way.

class Board(object):
    '''Creates a board object with a print board method.'''

    def __init__(self, sides=11):
        self.sides = sides
        self.storedBoard = {(x,y):'W' for y in range(1,self.sides) for x in range(1,self.sides)}

    def print_board(self):
        printableBoard = collections.OrderedDict(sorted(self.storedBoard.items()))
        for y in range(1, self.sides):
            print ' '.join(str(printableBoard[x, y])[0] for x in range(1, self.sides))

I still do not know how I am going to completely implement ship damage or how it is tracked but I think this is a fairly good start. Right now though this lets me place the board and then I can run my ship placement script and it changes the 'W' value to the ship description.

Answer 1

Are you looking for something like this?

for y in range(1, 11):
    print ' '.join(board[x, y] for x in range(1, 11))

Here's a simpler method only using for loops:

for y in range(1, 11):
    for x in range(1, 11):
        # print the value followed by a single space
        print board[x, y],

    # print a new line
    print

Answer 2

I'd advise using classes for something like this. I have reimplemented your code to reflect the change:

import collections 
class Board(object):
    def __init__(self, sides=11):
        self.sides = sides
        u_board = {(x,y):'W' for y in range(1,self.sides) for x in
                range(1,self.sides)}
        self.board = collections.OrderedDict(sorted(u_board.items()))

    def print_board(self):
        for y in range(1, self.sides):
            print ' '.join(self.board[x, y] for x in range(1, self.sides))



# Usage

b = Board()
b.print_board()

Output:

$ python board.py
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W
W W W W W W W W W W

EDIT Modified print function to use @grc 's method
