是否有可能允许程序用户在从程序得到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，但是在程序的第一部分运行后我遇到了运行问题。如果不清楚，请告诉我。到目前为止我的代码是：

如果您需要打开的所有文件都可以从中央位置访问，那么您可以让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'
依此类推其他文件。
然后，不要告诉他们打开什么，只需用os.system()打开它：
os.system(t_test)
不要忘记import os使用其余的导入。

我自己想出来，当然还有互联网的帮助。我的更新代码是：

except:

for row in data:
colnum = 0
