如何在 Python 中创建一个简单的消息框? [英] How can I create a simple message box in Python?

问题描述

我正在寻找与 JavaScript 中的 alert() 相同的效果.

I'm looking for the same effect as alert() in JavaScript.

今天下午我使用 Twisted.web 编写了一个简单的基于 Web 的解释器.你基本上是通过一个表单提交一段 Python 代码，然后客户端来抓取它并执行它.我希望能够制作一个简单的弹出消息，而不必每次都重新编写一大堆样板 wxPython 或 TkInter 代码(因为代码通过表单提交然后消失).

I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears).

我试过 tkMessageBox:

I've tried tkMessageBox:

import tkMessageBox
tkMessageBox.showinfo(title="Greetings", message="Hello World!")

但这会在后台打开另一个带有 tk 图标的窗口.我不要这个.我正在寻找一些简单的 wxPython 代码，但它总是需要设置一个类并进入一个应用程序循环等.在 Python 中没有简单的、无捕获的方法来制作消息框吗?

but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

推荐答案

您可以使用这样的导入和单行代码:

You could use an import and single line code like this:

import ctypes  # An included library with Python install.   
ctypes.windll.user32.MessageBoxW(0, "Your text", "Your title", 1)

或者像这样定义一个函数(Mbox):

Or define a function (Mbox) like so:

import ctypes  # An included library with Python install.
def Mbox(title, text, style):
    return ctypes.windll.user32.MessageBoxW(0, text, title, style)
Mbox('Your title', 'Your text', 1)

注意样式如下:

##  Styles:
##  0 : OK
##  1 : OK | Cancel
##  2 : Abort | Retry | Ignore
##  3 : Yes | No | Cancel
##  4 : Yes | No
##  5 : Retry | Cancel 
##  6 : Cancel | Try Again | Continue

玩得开心！

注意:编辑为使用 MessageBoxW 而不是 MessageBoxA

Note: edited to use MessageBoxW instead of MessageBoxA
