【问题描述】：

是否可以允许程序用户在他们从程序得到关于他们应该使用哪个测试的答案后上传他们的数据？我知道我需要使用 tkFileDialog 但在程序的第一部分运行后我无法运行它。如果不清楚，请告诉我。到目前为止，我的代码是：

【问题讨论】：

定义“上传”。用户从文件对话框中选择文件后，数据应该发生什么？
长期目标是使用他们选择的文件来运行他们被告知最适合他们的数据的任何统计程序。现在，我需要能够让他们选择他们想要使用的文件。
在回答完所有问题后，您希望打开 2-prop 测试吗？如果是，这些是否存储在每个人都可以访问的位置（例如服务器或每个人都使用一台计算机）？
我下面的回答解决了你的问题吗？

标签： python file-upload tkinter filedialog

【解决方案1】：

如果您需要打开的所有文件都可以从一个中心位置访问，您可以让您的if 语句打开他们需要的文件。

尝试将这些文件设置为变量：

t_test = r'Path\To\File\location\t-test.file'

其他文件以此类推。

然后，不要告诉他们要打开什么，而是用os.system()打开它：

os.system(t_test)

不要忘记 import os 与您的其余导入。

【讨论】：

不是真的，这是我的错，因为我的问题并没有应有的清晰。我想到了。我添加了一个按钮来浏览我的计算机或用户计算机上的文件。谢谢你的尝试。我会发布我的代码。
您的解决方案似乎让用户浏览文件。如果您想确保用户正在打开正确的文件。如果您使用 tkinter 应用程序打包文件，您可以强制用户打开正确的文件，因为他们的路径总是相同的。

【解决方案2】：

我自己想通了，当然是在互联网的帮助下。我更新的代码是：

    global sample
    if fname:
        print "uploading file...",fname
        try:
            print("""Here comes the file""")
        except:
            showerror("Open Source File", "Failed to read file\n'%s'" % fname)

您的帖子格式错误。请您花几分钟时间来解决它吗？
如果它只是为了你没关系，但如果你让其他人接触代码，你应该把你所有的导入放在你模块的顶部。查看更多关于格式化的信息：python.org/dev/peps/pep-0008/#imports
