從另一個文件導入編碼到一個新的tkinter

Question

我有一個文件叫wckcalendar.py。我想導入這個日曆，到另一個tkinter qw.py它有一個按鈕。我想同時顯示從wckcalendar文件的按鈕和日曆Tkinter的。

，但我得到的錯誤是：

File "C:/Python27/qw.py", line 1, in <module> 
    import wckCalendar 
    File "C:/Python27\wckCalendar.py", line 115, in <module> 
    root.mainloop() 
NameError: name 'root' is not defined 
>>> 

問題：我沒有得到顯示在同一window.Please幫助我的按鈕和日曆！ qw.py

我什麼在代碼中看到一些其他問題，如函數保持對象的局部變量：在函數返回後它們將被垃圾收集
