Tkinter FileDialog

Question

Возможно ли разрешить пользователю программы загружать свои данные после того, как они получили ответ от программы о том, какой тест они должны использовать? Я знаю, что мне нужно использовать tkFileDialog, но у меня возникли проблемы с запуском после завершения первой части программы. Дайте мне знать, если это неясно. Мой код до сих пор является:

Я понял это самостоятельно, с некоторой помощью из Интернета, конечно. Мой обновленный код:

from Tkinter import * 
import tkMessageBox 
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

      #will do t-test here 
      print sample 
      # now sample list contains the data for doing t-test, 
      #you just need to call t-test to get the results and show it on message box

Answer 2

Если все файлы, необходимые для открытия доступны из центрального расположения, вы могли бы ваше if заявление открыть файл им необходимую для них.

Попробуйте установить эти файлы в качестве переменных:

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

и так далее для остальных файлов.

Затем, вместо того, чтобы говорить им, что открыть просто открыть его с os.system():

os.system(t_test)

Не забудьте import os с остальной частью Вашего импорта.
