我需要幫助。我正在開發與tkinter的界面。在某個時候，當我在窗口中插入一個按鈕時，它不能正常工作，實際上，這是行不通的。我給我這個錯誤，當我按下按鈕：Python 3（.5.2）Tkinter
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/tkinter/__init__.py", line 1550, in __call__
return self.func(*args)
File "/Users/Edoardo/Desktop/Progetti/Programming Projects/Python Projects/Encoder 1.0 alpha.py", line 277, in <lambda>
encode = Button(text="ENCODE", command=lambda: encode())
TypeError: 'Button' object is not callable
這是代碼（部分缺失的原因，之前寫整個程序，我想確保它的工作原理）：
from tkinter import *
import tkinter.messagebox
# encode = {char : code}

如果你移動_only_'root.mainloop（）'，你會得到'NameError'，因爲你試圖調用的函數沒有被定義。這就是爲什麼我說「你應該移動你的函數定義」，它解決了NameError和mainloop。 – Lafexlos
它不會導致「naemerror」，因爲在該代碼中包含一個「lambda」表達式：它將僅在「點擊時間」進行評估。 – jsbueno
哦拍。完全錯過了。你說得對，對不起。 :) – Lafexlos
