PySimpleGUI - 我无法在浏览器上获得任何输出

Question

这段代码计算用户在给定日期的班次。 3 x 班次（早、晚、晚）每 5 周轮换一次。每个班次都有 2 个技术团队。第 1 队进行周日至周四轮换工作 第 2 队进行周二至周六轮换工作

使用 PySimpleGUI 实现了一个 GUI，以使代码更加用户友好。 我尝试使用 PySipmleGUIWeb 在我的网络浏览器中运行它。

在浏览器中启动应用程序时，我可以毫无问题地选择日期、班次等。只要我点击提交按钮，实际上什么都没有发生，我在 Pycharm 控制台中得到以下输出：

Returned from Remi Start command... now sending None event

试图摆脱结果的弹出窗口并尝试仅打印它们。我没有收到任何错误，但只有 PyCharm 控制台而不是 Web 浏览器中的结果。

知道如何使用 PySimpleGUIWeb 完成这项工作吗？

非常感谢。

Answer 1

问题是

window.close()

在第 24 行使用。将它移到第 111 行，现在这就像一个魅力。
