Question

当我在IDLE中运行我的脚本时它运行完美，但是当我将其保存为.py文件并尝试从文件夹中打开它时，它会闪烁一秒钟然后立即关闭。为什么会发生这种情况？我该如何解决？

#   average.py
def main():
    print("This program will calculate your final grade for the class.")
    assignment1= eval(input("What is your assignment 1 score?"))
    assignment2= eval(input("What is your assignment 2 score?"))
    assignment3= eval(input("What is your assignment 3 score?"))
    assignment4= eval(input("What is your assignment 4 score?"))
    assignment5= eval(input("What is your assignment 5 score?"))
    assignment6= eval(input("What is your assignment 6 score?"))
    assignment7= eval(input("What is your assignment 7 score?"))
    assignment8= eval(input("What is your assignment 8 score?"))
    assignment9= eval(input("What is your assignment 9 score?"))
    assignment10= eval(input("What is your assignment 10 score?"))
    midterm= eval(input("What is your midterm exam score?"))
    final=eval(input("What is your final exam score?"))
    participation= eval(input("What is your participation score?"))
    average= (((assignment1 + assignment2 + assignment3 + assignment4 + assignment5 + assignment6 + assignment7 + assignment8 + assignment9 + assignment10 + midterm + final + participation)/420)*100)
    print("You final class grade is", average)

Answer 1

添加样板：

if __name__ == '__main__':
    main()

在你的代码之后。

Answer 2

首先应打开命令提示符，然后将脚本拖到其上以运行它。否则当程序结束时窗口关闭。

编辑：并执行@sundance建议的内容。

Answer 3

首先，您是否正在调用main函数？我的意思是，你是否在代码的末尾添加了main()？如果是，问题是python IDLE运行脚本然后等待执行新代码。 python.exe不是这种情况。你必须让翻译等待。执行此操作的常用方法是在代码末尾添加行raw_input()，这将强制解释器在关闭之前等待（不需要的）用户输入，从而将结果打印到屏幕，直到有人输入某些内容为止进入它并按下返回。

Answer 4

@sundance是对的。您的代码只定义了一个函数，但从不调用它，因此运行脚本时没有任何反应。你需要调用函数来执行它的主体，因此需要main()调用。

另外，您的代码可以按如下方式进行优化：

tasks = ['assignment {}'.format(i) for i in range(1, 11)] + [
    'midterm exam', 'final exam', 'participation']
sum_scores = sum(
    float(input('What is your {} score? '.format(task)))
        for task in tasks)
average = sum_scores / 420 * 100
print('Your final class grade is', average)

Answer 5

在average.py中，您只是定义函数。因此，当您执行脚本时，只有函数定义而没有函数调用。您需要在脚本末尾调用main()函数。只需在代码末尾添加main()

即可
