尝试创建一个组合框，从2016年开始关注youtube教程，为我的学校工作制作一个货币计算器。
box = ttk.Combobox(LeftMainFrame, textvariable=value0, state='readonly',font=('arial', 20, 'bold'),width=20)
box['values'] = (' ', 'USA', 'Kenya', 'Brazil', 'Canada', 'India', 'Phillappines')
box.current(0)
box.grid(row=4, column=2)
一直说ttk没有定义。
我对python一无所知 我也在使用visual studio
答案 0 :(得分：0)
来自python's ttk doc (python 2)或same for python 3：
要开始使用Ttk，请导入其模块：

}但是像这样的代码：
import ttk
可以选择使用它：
from Tkinter import *
然后几个ttk小部件（Button，Checkbutton，Entry，Frame，Label，LabelFrame，Menubutton，PanedWindow，Radiobutton，Scale和Scrollbar）将自动替换Tk小部件。
因此，根据您的环境，您可能需要导入ttk：
from Tkinter import *
from ttk import *
