更改此：

for index in range(8):
    n = words[index]
    button = Button(root,text = n,command = lambda index = index,n = n: disable(buttons,index,n)).pack(side = 'left')
    buttons.append(button)

对此：

for index in range(8): 
    n = words[index]
    button = Button(root,n))
    button.pack(side = 'left')
    buttons.append(button)

您看到的问题是由于在创建按钮的同一行上使用了几何管理器pack()。当所有几何图形管理器都返回None时，如果您尝试编辑按钮，则会收到该错误。

那表示如果您这样编写循环，可能会更好：

# Use import as tk to avoid any chance of overwriting built in methods.
import tkinter as tk

root = tk.Tk()
words = ["lst","while","for","i",":","lst.pop()","in","range(lst)"]
buttons = []

# Use the list to set index.
for ndex,word in enumerate(words):
    # Append the button object to the list directly
    buttons.append(tk.Button(root,text=words[ndex]))
    # Us the lambda to edit the button in the list from the lambda instead of a new function.
    # A useful trick is to use `-1` to reference the last index in a list.
    buttons[-1].config(command=lambda btn=buttons[-1]: btn.config(state="disabled"))
    buttons[-1].pack(side='left')

if __name__ == '__main__':
    root.mainloop()

我相信index是内置方法。
