Question

再次来到社区！如何在Python 3上使用Tkinter打开LibreOffice或Word文件（在我的Mac上，但最终也是Windows）。我的UI有几个按钮，我想与特定文件关联，按下该按钮时，它应该将命令发送到Brother打印机并打印出该文件。当我在这里时，我还想知道是否有一个脚本来检测用户正在使用的操作系统，并使用Tkinter执行单独的命令（因为Mac和Windows有不同的要求）。我的代码如下。

注意：如果您查看“SignOut”功能，它会将所有内容搞砸。这就是评论的原因。

您可以使用platform模块来检测操作系统。像这样：

import platform
print platform.system()
# Windows / Linux
if platform.system() == "Windows":
    # Do this
if platform.system() == "Linux":
    # Do this differently

您可以使用command参数为tkinter.Button创建回调：

 new_button = Button(master, text = "Some button", command = function)

对于Word文档，您可以使用python-docx，您可以找到文档here。确实需要在不同平台上以不同方式打印文件。您可以找到答案here。
