Question

当我在Pycharm上运行时，它打开后立即关闭。而在视频教程中它始终保持打开状态，为什么？

import pygame

pygame.init()

win = pygame.display.set_mode((500, 500))

pygame.display.set_caption("hello")

我正在使用Windows操作系统，python版本3.7.2和pygame 1.9.4

I don't know which tutorial you talk about, but if the process that created the window finishes, the window will be closed.

E.g. when you create the window via a python shell, the window will stay open as long as the shell is open.

If you open the window via a script (a file), you need to keep the script from finishing. You do this by creating what is called a main loop and usually looks like this:

import pygame

def main():
    pygame.init()

    win = pygame.display.set_mode((500, 500))

    pygame.display.set_caption("hello")

    clock = pygame.time.Clock()

    while True:
        for e in pygame.event.get():
            if e.type == pygame.QUIT:
                return
        win.fill((30, 30, 30))
        pygame.display.update()
        clock.tick(60)

if __name__ == '__main__':
    main()
    pygame.quit()

我遇到了与您相同的问题（并且我遵循的是同一教程），我发现如果将整个内容括在while循环中（不包括 import pygame ， pygame）。 init（）和用于while循环的变量）效果很好。

import pygame

pygame.init()

Game = True

while Game is True:
    window1 = pygame.display.set_mode((500, 500))
    pygame.display.set_caption("First Game")

我刚刚开始学习Python，所以这可能不是最好的方法，但我希望它会有所帮助：）

Pygame的窗口打开后立即关闭，为什么？
