从文本文件中读取行并在数组中绘图

Question

我正在尝试创建一个类似于战舰的程序，除了将骨头放在后院内。用户将不得不猜测骨骼的行和列位置（就像在战舰中一样）。

我希望程序从文本文件中读取代码行并使用这些值将它们绘制在我的网格上（不修改文本文件）。不过我不知道该怎么做。

以下是文本文件的组成：

12 12 4 4
0 7 0 8 0 9 0 10
2 4 3 4 5 4 6 4
0 0 1 0 2 0 3 0
11 11 10 11 9 11 8 11

第 1 行包含网格的宽度 (12) 和高度 (12)，骨骼的数量 (4) 和骨骼的长度 (4)。 第 2 到 5 行包含我们 4 个骨骼的位置，格式如下：

<cell1_row> <cell1_col> <cell2_row> <cell2_col> <cell3_row> <cell3_col><cell4_row> <cell4_col>

到目前为止，我已经掌握了它应该是什么样子的基本结构，但我缺少一些核心功能。

我想知道如何从文本文件中读取游戏数据并在我的程序中使用。

def getData(gameFile):
    """Pulling our bone information from the game text file"""
    file = open (gameFile, 'r')
    gameData = [line.strip('\n').split(' ') for line in file.readlines()]

不确定这是否是正确使用它的方法^。下面是我开始做的工作！

#variables
bones = list()
backyardWidth = 12
backyardHeight = 12
numOfBones = 4
boneLength = 4
gameFile = "FBI_the_Game_Data_2.txt"

def createBackyard(aWidth, aHeight):
    """ Create and return an empty "backyard" of aWidth by aHeight."""
    aBackyard = [ [ " . " for i in range(backyardWidth) ] for j inrange(backyardHeight) ]   
    return aBackyard

def displayBackyard(aBackyard, aWidth, aHeight):
    """Creates a backyard with no bones."""
    print("\nThere are 4 bones, each are 4 cells long, buried in this backyard! Can you find them?")
    aString = " "
    for column in range(0, aWidth):
        aString = aString + str(column) + " "
        if len(str(column)) == 1 :
            aString += " "           
    print(aString)
    for row in range(0, aHeight):
       print(unpack(aBackyard, row))

def unpack(aBackyard, row):
    """ Helper function.
        Unpack a particular row of the backyard, i.e., make a string out of it.
    """
    aString = ""
    for i in range(backyardWidth):
        aString += aBackyard[row][i]
    # Add a column (from 1 to aHeight) to the right of a backyard row
    aString = aString + " " + str(row)
    return aString

# main
print("""Welcome to Fast Bone Investigation (FBI) the game.
In this game, we dig out bones from Mrs. Hudson's backyard!""")

# Create backyards     
displayedBackyard = createBackyard(backyardWidth, backyardHeight)

# Display the backyard
app_on = True

while app_on:
    displayBackyard(displayedBackyard, backyardWidth, backyardHeight)

    choice = input(("""\nTo do so, please, enter the row and the column number of a cell in which you suspect a bone is buried
(e.g., 0 3 if you suspect that part of a bone is buried on the first row at the 4th column).
Enter -1 to quit: """))

    # if user enters nothing
    if len( choice ) == 0 :
        print("***You have not entered anything. You need to enter a valid row and the column number!\n")
    elif len( choice ) == 1 :
        print("***You have entered only 1 value. You need to enter a valid row and the column number!\n")
    elif choice == "-1":
        app_on = False
    # if the user enters any alphabet     
    elif choice.isalpha( ):
        print("***You have entered %s. You need to enter a valid row and the column number!\n" %choice)
    elif "." in choice :
        print("***You have entered %s. You need to enter a valid row and the column number!\n" %choice)
    else:
        userGuess = int(choice)
        if userGuess > backyardHeight or backyardWidth or userGuess < 0:
            print("You needed to enter a row and column number of a cell that is within the backyard!\n")

##   Unfinished Beeswax
##      elif choice == 
##            print("****HIT!!!!****")
        else:
            print("****OOPS! MISSED!****")

print("\nWasn't it fun! Bye!")

在程序开始时，所有骨头现在都应该被掩埋，玩家无法看到。然后，随着游戏的执行，玩家被要求猜测 通过输入行号和列号来掩埋骨头 后院的一个牢房。如果该单元格中确实埋有骨头部分，则该部分骨头在该单元格中显示为“B”。

以下是程序执行的示例：

Answer 1

你可以这样做：

def getData(gameFile):
    """Pulling our bone information from the game text file"""
    file = open (gameFile, 'r')
    gameData = [line.strip('\n').split(' ') for line in file.readlines()]
    backyardWidth = int(gameData[0][0])
    backyardHeight = int(gameData[0][1])
    nbBones = int(gameData[0][2])
    boneLength = int(gameData[0][3])
    bones = []
    for i in range(nbBones):
        bones.append([int(gameData[i+1][j]) for j in range(boneLength*2)])
    return backyardWidth, backyardHeight, nbBones, boneLength, bones

如果你 print getData('FBI.txt') 这返回：

(12, 12, 4, 4, 
[[0, 7, 0, 8, 0, 9, 0, 10], [2, 4, 3, 4, 5, 4, 6, 4], [0, 0, 1, 0, 2, 0, 3, 0], [11, 11, 10, 11, 9, 11, 8, 11]])

Answer 2

为了从文件中读取您的游戏设置，您的getData() 函数需要返回它已读入的数据。从文件中读取时， 最好使用 Python 的 with 命令，它可以确保文件在使用后始终正确关闭。

gameData 然后保存一个列表列表，文本文件中的每一行都有一个列表。第一行（第 0 行）保存您的参数，其余行保存骨骼位置。 这些都可以按如下方式分配给您的变量：

def getData(gameFile):
    """Pulling our bone information from the game text file"""

    with open(gameFile) as f_input:
        gameData = [line.strip('\n').split(' ') for line in f_input.readlines()]

    return gameData

gameData = getData("FBI_the_Game_Data_2.txt")

#variables
backyardWidth, backyardHeight, numOfBones, boneLength = gameData[0]
bones = gameData[1:]

因此，使用您的示例文本文件，您的变量将包含以下值：

backyardWidth = 12
backyardHeight = 12
numOfBones = 4
boneLength = 4

bones = [['0', '7', '0', '8', '0', '9', '0', '10'], ['2', '4', '3', '4', '5', '4', '6', '4'], ['0', '0', '1', '0', '2', '0', '3', '0'], ['11', '11', '10', '11', '9', '11', '8', '11']]

然后您需要正确处理这些数据。
