从 CLI 运行时阻止 python GUI 程序退出

如何在 OS X 上轻松制作阻塞 GUI 应用程序？

我有一个简单的 python 绘图程序。当我从现有的 python 交互式会话内部或从 iPython 中运行它时，会显示 GUI 窗口，我可以看到它并与其交互。当我从 CLI 运行 .py 文件时，GUI 会闪烁并立即关闭。

我想从命令行运行它并保留 GUI。

if __name__ == "__main__":
    import matplotlib
    from matplotlib import pyplot
    data = range(1,10)
    fig = pyplot.plot(data)
    pyplot.show()

How can easily I make a blocking GUI app on OS X?

I have a simple python plotting program. When I run it from inside an existing python interactive session, or from within iPython, the GUI window is displayed, and I can see it and interact with it. When I run the .py file from the CLI, the GUI flashes and closes immediately.

I would like to run this from the command line and have the GUI remain.

if __name__ == "__main__":
    import matplotlib
    from matplotlib import pyplot
    data = range(1,10)
    fig = pyplot.plot(data)
    pyplot.show()

听起来好像交互模式已以某种方式启用，尽管我不确定在哪里。试试这样：

def main():
    import matplotlib.pyplot as plt
    data = range(1,10)
    fig = plt.plot(data)
    plt.ioff()  # turns interactive mode OFF, should make show() blocking
    plt.show()


if __name__ == "__main__":
    main()

It sounds as though interactive mode has been enabled somehow, although I'm not sure where. Try it like this:

def main():
    import matplotlib.pyplot as plt
    data = range(1,10)
    fig = plt.plot(data)
    plt.ioff()  # turns interactive mode OFF, should make show() blocking
    plt.show()


if __name__ == "__main__":
    main()
