Python程序直接运行时终端意外关闭问题求助

嘿，我完全懂你的困扰——PyCharm里运行游戏一切正常，能看完结果、等你按回车才退出，但直接双击.py文件时，刚猜对数字窗口就秒关，连得分榜都来不及看。咱们一步步搞定这个问题：

第一步：修复代码里的文件操作隐患 #

你的代码里连续打开了两次Score.txt，但第一次打开的文件句柄没关闭，这可能导致写入的内容还留在内存缓冲区，没及时存到磁盘，甚至干扰后续的读取操作。咱们用Python的with语句来处理文件，它会自动帮我们关闭文件，既安全又省心：

替换原来的文件读写部分：

# 写入玩家得分到文件
with open("Score.txt", "a") as score_file:
    score_file.write(f"Player: {playerName} | Guesses: {inputCounter}\n")

# 读取并显示当前玩家的历史得分
print("\nHere is your score list :")
lineNumber = 0
with open("Score.txt", "r") as score_file:
    for line in score_file:
        line = line.strip()
        if playerName in line:
            lineNumber += 1
            # 用split提取得分，比rfind更直观
            score = line.split(" ")[-1]
            print(f"Attempt #{lineNumber} | Score: {score}")

第二步：解决窗口闪退的核心问题 #

即使加了input()，Windows下双击运行有时还是会闪退，这通常是因为输出缓冲区没来得及刷新，或者程序隐藏了小错误导致提前崩溃。咱们做两个优化：

1. 强制刷新输出缓冲区 #

在最后的等待输入语句前，先强制刷新所有输出内容，确保它们都显示在窗口里：

import sys

# ... 你的游戏逻辑代码 ...

# 强制刷新所有输出，避免内容还在缓冲区就关闭窗口
sys.stdout.flush()
input("\nPress any key to exit... ")

2. 添加异常处理，避免程序崩溃 #

如果玩家输入了非数字内容（比如字母），你的代码会直接报错崩溃，导致窗口瞬间关闭。咱们给输入部分加个异常捕获：

while playerNumber != randomNumber:
    try:
        playerNumber = int(input("Please guess a whole number from 1 to 100: "))
    except ValueError:
        print("Oops! Please enter a valid whole number, try again.")
        continue
    inputCounter += 1
    if playerNumber < randomNumber:
        print("The number you have entered is LOWER than the generated number, please try again!")
    elif playerNumber > randomNumber:
        print("The number you have entered is HIGHER than the generated number, please try again!")

完整修改后的代码 #

把这些优化整合起来，最终代码如下：

import random
import sys

inputCounter = 0
lineNumber = 0
playerNumber = 0
randomNumber = random.randint(1, 100)
playerName = input("Please enter your name: ")

while playerNumber != randomNumber:
    try:
        playerNumber = int(input("Please guess a whole number from 1 to 100: "))
    except ValueError:
        print("Oops! Please enter a valid whole number, try again.")
        continue
    inputCounter += 1
    if playerNumber < randomNumber:
        print("The number you have entered is LOWER than the generated number, please try again!")
    elif playerNumber > randomNumber:
        print("The number you have entered is HIGHER than the generated number, please try again!")

print()
if inputCounter > 1:
    print(f"You won with {inputCounter} guesses")
else:
    print("CONGRATS! You won with 1 guess!!")

# 写入玩家得分
with open("Score.txt", "a") as score_file:
    score_file.write(f"Player: {playerName} | Guesses: {inputCounter}\n")

# 读取并展示历史得分
print("\nHere is your score list :")
lineNumber = 0
with open("Score.txt", "r") as score_file:
    for line in score_file:
        line = line.strip()
        if playerName in line:
            lineNumber += 1
            score = line.split(" ")[-1]
            print(f"Attempt #{lineNumber} | Score: {score}")

# 确保所有内容显示后再等待用户输入
sys.stdout.flush()
input("\nPress any key to exit... ")

这样修改后，双击.py文件运行游戏，窗口就会在显示完所有结果后，等你按任意键再关闭，和PyCharm里的体验完全一致啦！
