Question

我如何将它放在python的循环中，以便它不断询问玩家1是否赢得了比赛，直到它达到了比赛中的游戏数量。我尝试了一段时间但它没有工作:(

Y="yes"
N="no"
PlayerOneScore=0
PlayerTwoScore=0

NoOfGamesInMatch=int(input("How many games? :- "))
while PlayerOneScore < NoOfGamesInMatch:
    PlayerOneWinsGame=str(input("Did Player 1 win the game?\n(Enter Y or N): "))

if PlayerOneWinsGame== "Y":
     PlayerOneScore= PlayerOneScore+1
else:
     PlayerTwoScore= PlayerTwoScore+1

print("Player 1: " ,PlayerOneScore)
print("Player 2: " ,PlayerTwoScore)

print("\n\nPress the RETURN key to end")

Answer 1

while循环可以正常工作

while PlayerOneScore < NoOfGamesInMatch:
    PlayerOneWinsGame=str(input("Did Player 1 win the game?\n(Enter Y or N): "))

    if PlayerOneWinsGame== "Y":
        PlayerOneScore= PlayerOneScore+1
    else:
        PlayerTwoScore= PlayerTwoScore+1

将其他所有内容排除在外。意思是在循环之前保留初始化内容，然后在循环之后报告分数。

Answer 2

import sys    
while PlayerOneScore < NoOfGamesInMatch:
    answer = str(input("Did Player 1 win the game?\n(Enter Y or N or Q to quit): "))

    if answer.lower() == "q":
        sys.exit()
    elif answer.lower() == "y":
        PlayerOneScore = ( PlayerOneScore + 1 )
    elif answer.lower() == "n":
        PlayerTwoScore = ( PlayerTwoScore + 1 )
    else
        print "Valid answers are Y (yes), N (no) and Q (quit).

您现在可以输入q离开游戏。我也是这样做的，所以答案不区分大小写。

只要PlayerOneScore小于NoOfGamesInMatch，游戏就会开始。

您应该将导入系统放在文件的顶部。
