如何让循环重复执行我的nims

Question

# importing random module, for random choices
import random

# print_move function to display CPU and players current move
def print_move(current_player, row, stick_quantity):
    current_player = current_player
    if stick_quantity == 1:
        print(f"{current_player} takes {stick_quantity} sticks from {row} row")
    else:
        print((f"{current_player} takes {stick_quantity} sticks from {row} row"))
        

# beginning of nims game, choosing who will choose  
print("Welcome to Nim!")
name = input("Enter name: ")
current_player = random.choice([name, "CPU"])
print('game is starting',(current_player),'will be going first')

# create stick lists
sticks = [1, 3, 5, 7]

# looping the sticks 
def nims():
    for count, stick in enumerate(sticks):
        print(count+1, stick * "|")

# loop that breaks when the number of sticks are less than 0
while sum(sticks) > 0:
    nims()

    if current_player == name:
# exception handling so that the user inputs the correct amount of sticks/rows
        while True:
            try:
                row = int(input("Which row would you like to take sticks from? "))
                stick_quantity = int(input("How many sticks would you like to take? "))
                if 1 <= row <= len(sticks) and 1 <= stick_quantity <= sticks[row-1]:
                    break
                else:
                    print("")
                    print("Invalid input, please enter a valid row, and or a valid amount of sticks")
            except ValueError:
                print("")
                print("Invalid input, please enter a valid row, and or a valid amount of sticks")

        sticks[row - 1] -= stick_quantity
        print_move(current_player,row,stick_quantity)
        if current_player == name:
            current_player = "CPU"
        else:
            current_player = name
    
    else:
        # handling value error in the stick_quantity variable
        try:
            row = random.randint(1, len(sticks))
            stick_quantity = random.randint(1, sticks[row-1])
            sticks[row-1] -= stick_quantity
            print_move(current_player,row,stick_quantity)
            if current_player == "CPU":
                current_player = name
            else:
                current_player = "CPU"
        except ValueError:
            print("")


winner = current_player
print("Winner is", winner)

我在Python中创建了一个Nims游戏，整体运行得很好，但我在循环重复这部分遇到了一些问题。我想在游戏结束后，宣布获胜者，然后问玩家是否想再玩一次。如果玩家输入'y'，那么Nims游戏就会重新开始；如果玩家按'n'或者其他任何键，游戏就结束，并显示玩家的胜负记录。

我不太确定是不是应该在Nims游戏开始时就用一个类似于While play_again == 'y':的循环。我试过这样做，但似乎不太奏效。我还尝试了其他方法，但到目前为止，它们都没有很好地解决问题。任何帮助或指导都将非常感谢。提前谢谢你们。

你可以试试这样的做法：

print("Welcome to Nim!") 
name = input("Enter name: ") 
replay = 'y' 

while replay == 'y':

然后在游戏结束的时候：

winner = current_player print("Winner is", winner)
replay = str(input("One more round (y/n)?"))
