我的while循环在6次循环后停止，尽管它应该永远继续下去

Question

我正在用python编写一个叫做坦克的游戏，本来应该有50轮，但只有6轮就停止了，有人能告诉我发生了什么吗？它也意味着当用户得分达到10分时停止，因为只有6轮，因此它不可能因此而停止。

下面是我的代码：

#Tanks problem
import random

Grid = [["" for X in range(8)] for Y in range(8)]

PlacePicked=[]

#subroutine to place tanks
def TankPlace():
    global Grid
    for I in range(0,10,1):
        while True:
            X=random.randint(0,7)
            Y=random.randint(0,7)
            if Grid[X][Y]=="T":
                pass
            else:
                Grid[X][Y]="T"
                break

#subroutine to output places already picked
def OutputPlacePicked():
    global PlacePicked
    Places=""
    if len(PlacePicked)==0:
        pass
    else:
        for I in range(0,len(PlacePicked),1):
            Places=Places+PlacePicked[I]+", "
        print("\nSo far you have picked the coordinates of {}".format(Places[:-2]))

#subroutine to check if inputted coordinate is a tank or not
def GameInput(X,Y):
    X1=X-1
    Y1=Y-1
    global Grid
    global PlacePicked
    while True:
        if "({} ,{})".format(X,Y) in PlacePicked:
            print("\nYou have already chosen ({}, {})".format(X, Y))
            X=int(input("\nWhat is your X coordinate?\n"))
            Y=int(input("\nWhat is your Y coordinate?\n"))
        elif Grid[X1][Y1]=="T":
            print("\nTank Hit!")
            PlacePicked.append("({} ,{})".format(X, Y))
            tank="True"
            return tank
        else:
            print("\nTank Missed!")
            PlacePicked.append("({} ,{})".format(X, Y))
            tank="False"
            return tank


#maincode
print("Welcome to Tanks!\n")
print("Instructions:\n-Tanks is a game for 1 player.\n-At the start of the game, the computer places 10 tanks on an 8x8 board but does not\nreveal their locations to the player.\n-Each tank occupies one square on the board.\n-The player enters a grid reference, e.g. (1,5) on each turn.\n-The player destroys the tank if the square is occupied by a tank.\n-The player wins if they destroy all the tanks within 50 turns.")
go=0
score=0
while True:
    TankPlace()
    OutputPlacePicked()
    GameInput(int(input("\nWhat is your X coordinate?\n")), int(input("\nWhat is your Y coordinate?\n")))
    if GameInput=="True":
        score=score+1
    elif GameInput=="False":
        pass
    if score==10:
        print("You Win!")
        break
    else:
        pass
    if go==50:
        print("You Lose")
        break
    else:
        pass
    go=go+1

有人能告诉我为什么会这样吗？

我对你的"main“做了一些修改：

#maincode
print("Welcome to Tanks!\n")
print("""Instructions:
  -Tanks is a game for 1 player.
  -At the start of the game, the computer places 10 tanks on an 8x8 board but does not
   reveal their locations to the player.
  -Each tank occupies one square on the board.
  -The player enters a grid reference, e.g. (1,5) on each turn.
  -The player destroys the tank if the square is occupied by a tank.
  -The player wins if they destroy all the tanks within 50 turns.""")
go=0
score=0
TankPlace()
while True:
    OutputPlacePicked()
    GameInput(int(input("\nWhat is your X coordinate?\n")), int(input("\nWhat is your Y coordinate?\n")))
    if GameInput=="True":
        score=score+1
    elif GameInput=="False":
        pass
    if score==10:
        print("You Win!")
        break
    else:
        pass
    if go==50:
        print("You Lose")
        break
    else:
        pass
    go=go+1

请注意，我在循环之前移动了对TankPlace()的调用；我认为每次移动都要重新放置坦克，这不会帮助玩家获胜。我还删除了global tank，因为它没有被使用。

无论如何，在那之后，我可以玩超过6个动作。然而，游戏过早地结束了，因为我猜到了一个9，然后产生了一个异常。对于下一个版本来说，检查用户的输入将是一个真正的改进。

我的猜测是GameInput与字符串"True“的比较。

我将允许您查找它，但我担心两个不同类型的比较将降级为bool类型的比较，并且如果int为非零且字符串为非空，则总是成功。
