Tkinter的问题

狗宁

部分代码如下：

1. def add_sutdent():
   
2.     new_root = Tk()
   
3.     new_root.title('学生注册')
   
4.     new_root.geometry('300x300')
   
5. 
   
6.     new_stu = Label(new_root, text='姓名>>>', font=('Heiti', 12)).grid(row=1, column=1)
   
7.     stu = StringVar()
   
8.     new_stu_entry = Entry(new_root, textvariable=stu, width=20).grid(row=1, column=2)
   
9. 
   
10.     new_pho = Label(new_root, text='电话>>>', font=('Heiti', 12)).grid(row=2, column=1)
    
11.     pho = StringVar()
    
12.     new_pho_entry = Entry(new_root, textvariable=pho, font=('Heiti', 12), width=20).grid(row=2, column=2)
    
13. 
    
14.     new_sex_choice = Label(new_root, text='性别>>>', font=('Heiti', 12)).grid(row=3, column=1)
    
15.     sex = StringVar()
    
16.     Radiobutton(new_root, text='male', variable=sex, value='male').grid(row=3, column=2, sticky='w')
    
17.     Radiobutton(new_root, text='female', variable=sex, value='female').grid(row=3, column=2, sticky='e')
    
18. 
    
19.     new_hob_choice = Label(new_root, text='爱好>>>', font=('Heiti', 12)).grid(row=4, column=1)
    
20.     hob_1 = IntVar()
    
21.     hob_2 = IntVar()
    
22.     Checkbutton(new_root, text='唱', variable=hob_1, onvalue=1, offvalue=0).grid(row=4, column=2, sticky='w')
    
23.     Checkbutton(new_root, text='跳', variable=hob_2, onvalue=1, offvalue=0).grid(row=4, column=2, sticky='e')
    
24. 
    
25.     new_pov_choice = Label(new_root, text='省份>>>', font=('Heiti', 12)).grid(row=5, column=1)
    
26.     pros = ['北京', '上海', '广州', '深圳']
    
27.     pro = StringVar()
    
28.     pro_choice = Combobox(new_root, textvariable=pro, width=15, values=pros, state='readonly').grid(row=5, column=2)
    
29. 
    
30.     def get_stu_info():
    
31.         stu_name = stu.get()
    
32.         stu_pho = pho.get()
    
33.         stu_sex = sex.get()
    
34.         stu_pro = pro.get()
    
35.         stu_like1 = hob_1.get()
    
36.         stu_like2 = hob_2.get()
    
37.         print(stu_name, stu_pho, stu_sex, stu_pro, stu_like1, stu_like2)
    
38. 
    
39.     button_4 = Button(new_root, text='提交', width=12, command=get_stu_info).grid(row=6, columnspan=3, pady=20)

问题是这样的，这个函数单独拿出来使用的话是正常的返回值，能打印出学生属性，但是放在项目里，返回的总是两个0，也就是所有的值都获取不到，这是什么问题呢？

单独拿出来测试的话是没有问题的
