Tkinter文件对话框

Question

在从程序中获得关于应该使用哪种测试的答案之后，是否可以允许程序用户上载数据？ 我知道我需要使用tkFileDialog，但是在程序的第一部分运行之后，我无法运行它。 让我知道是否不清楚。 到目前为止，我的代码是：

Answer 1

如果您需要从中央位置访问所有需要打开的文件， if可以让if语句打开它们所需的文件。

尝试将这些文件设置为变量：

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

其余的文件等等。

然后，不用告诉他们要打开什么，只需使用os.system()将其打开：

os.system(t_test)

不要忘记import os与其余import os一起导入。

我当然可以在互联网的帮助下自行解决。 我更新的代码是：

from Tkinter import *

from scipy import stats
import csv


sample=[]


def load_file():

    fname = askopenfilename(filetypes = (("Text Files", ".txt"),
                            ("HTML Files", "*.html;*.htm"),
                                ("All Files", "*.*")))
    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)
        ifile  = open(fname, "rb")

        data = csv.reader(ifile,delimiter=' ')

        rownum = 0

        for row in data:
            colnum = 0
            d=[]
            for col in row:
                print '%s' % col
                d.append(float(col))
                colnum += 1
            sample.append(d)
            rownum += 1

        ifile.close()
        print sample


def choose():

        global sample

            tkMessageBox.showinfo('t-test', 't-value is %s, p=%s' %stats.ttest_1samp(sample[0], 0.50 ))
            #will do t-test here
            print sample
            # now sample list contains the data for doing t-test,
