嗨，我是編程新手，我很抱歉，如果這是一個明顯的錯誤。我正在Mac OSX El Capitan上使用python 3.5編寫一個gui。這是迄今爲止代碼：python3 tkinter gui沒有迴應

from tkinter import * 
from tkinter import ttk 



class GUI(object): 
    def __init__(self, master): 
     master.title("Title") 
     master.resizable(False, False) 
     self.frame1 = ttk.Frame(master) 
     self.frame1.pack() 

     ttk.Label(text="Organism").grid(row=1, column=0) 

     self.organism_picker = ttk.Combobox(self.frame1, values=("Drosophila  melanogaster", 
                  "Danio rerio", 
                  "Caenorhabditis  elegans", 
                  "Rattus  norvegicus", 
                  "Mus musculus", 
                  "Homo sapiens")) 
     self.organism_picker.grid(row=2, column=0) 

     ttk.Label(text="Core gene symbol:").grid(row=3, column=0) 

     self.core = ttk.Entry(self.frame1) 
     self.core.grid(row=4, column=0) 


root = Tk() 
gui = GUI(root) 
root.mainloop()

當我運行該程序進入主循環，但從來沒有出現在GUI窗口和發射不reponding。我試圖重新安裝python 3，安裝了ActiveTcl，而不是嘗試使用ActivePython。堅果沒有一個工作。

非常感謝大家的回答。

與您的代碼唯一的問題是，你忘了附加兩個標籤到主窗口部件self.frame1。

爲了解決這個問題，修改它們如下：

#Attach the 2 labels to self.frame1 
ttk.Label(self.frame1,text="Organism").grid(row=1, column=0) 
ttk.Label(self.frame1,text="Core gene symbol:").grid(row=3, column=0)

演示

這樣做後，你會得到這樣的：

你不能使用包（）和電網（），因爲這將產生在此錯誤指出幾何經理衝突：

_tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack

嘗試改變：

self.frame1.pack()

到：

self.frame1.grid()

在這種情況下，我會建議使用包總體，因爲這是一個相當簡單的佈局。請參閱this guide：

When to use the Pack Manager

Compared to the grid manager, the pack manager is somewhat limited, but it’s much easier to use in a few, but quite common situations:

Put a widget inside a frame (or any other container widget), and have it fill the entire frame Place a number of widgets on top of each other Place a number of widgets side by side

最後：

Note: Don’t mix grid and pack in the same master window. Tkinter will happily spend the rest of your lifetime trying to negotiate a solution that both managers are happy with. Instead of waiting, kill the application, and take another look at your code. A common mistake is to use the wrong parent for some of the widgets.
