Python Tkinter单选按钮程序调试

Question

Essentially the program is a group of radio buttons and when the user clicks the submit button, the program should return the answer matching the string of choices made by the user. I've gotten it to work for the most part, but the decision made in the end is still wrong. Let me know if I can answer anymore questions.

Answer 1

You should use the get method when comparing Intvar instances and you need two arguments for your tkMessageBox.showinfo(title, message) function instead your passing only the title with no message so change your code to look like:

if q1.get() == 1 and q2.get() == 1 and q3.get() == 2 and q4.get() == 2 and  q5.get() == 1 and q6.get() == 2 and q7.get() == 2 and q8.get() == 2 and q9.get() == 2 :
    tkMessageBox.showinfo('Info','You should use the t-test!')

and also don't use sys.exit() to exit you program it will cause your program to be unresponsive instead use root.destroy()

Hopefully your message boxes should now be working as expected!

optional: use tkMessageBox.showerror(title, message) to display error messages

Answer 2

You should allow for not found conditions. Also lists make it easier to understand IMHO. The following should be self-explanatory. It only tests for the first 2 conditions with a third option for an easy test of the code, with print statements added for testing. You can expand from there. Also the use of lists or a function will greatly reduce the amount of "Label, Button, and Button" code.

from Tkinter import *
import tkMessageBox


def compare_lists(q_list, results_list):
    """ see if the radio buttons are in one of the results
        If so, return the number of the matching list
    """
    for ctr, sub_list in enumerate(results_list):
        if sub_list == q_list:
            print "Found", ctr, sub_list
            return ctr
    return -1

def choose():
    q_list = []
    results_list = [[1, 1, 2, 2, 1, 2, 2, 2, 2],
                    [1, 2, 1, 1, 2, 2, 2, 2, 2],
                    [1, 1, 1, 1 ,1 ,1 ,1 ,1 ,1]]
    print_list = ['You should use the t-test!',
                  'You should use the z-test!',
                  'Testing Only']
    for var in (q1, q2, q3, q4, q5, q6, q7, q8, q9):
        q_list.append(var.get())
    print q_list

    ## ctr = number of matching list and will print
    ## the same number in the print list
    ctr = compare_lists(q_list, results_list)
    if ctr > -1:
        result_label.set(print_list[ctr])
    else:
        result_label.set('Combination not found')
