我正在尝试用3个按钮创建一个窗口。当用户单击其中一个按钮时，调用分配的函数。这是我的代码，我从文档中阅读的内容尝试了所有内容，但我似乎无法克服它！

我还添加了程序调用的函数，它们完美地工作，只是添加它们以供参考。此外，按钮（）函数仅调用一次，它是一个没有参数的简单呼叫。

def buttons():
    root.geometry('1000x1000')

    btncreation = tkinter.Button(root, text='Order by Creation',
                                 command=creation)
    btncreation.pack()

    btnmodified = tkinter.Button(root, text='Order by Last Modified',
                                 command=lastmodified)
    btnmodified.pack()

    btnaccessed = tkinter.Button(root, text='Order by Last Accessed',
                                 command=lastaccessed)
    btnaccessed.pack()


def creation():
    lst.sort(key=os.path.getctime)
    num = 1
    for line in lst:
        dst = newpath + name + str(num) + suffix
        rename(line, dst)
        num += 1


def lastmodified():
    lst.sort(key=os.path.getmtime)
    num = 1
    for line in lst:
        dst = newpath + name + str(num) + suffix
        rename(line, dst)
        num += 1

按钮调用的函数：

def lastaccessed():
    lst.sort(key=os.path.getatime)
    num = 1
    for line in lst:
        dst = newpath + name + str(num) + suffix
        rename(line, dst)
        num += 1

另外，请不要对我的问题进行格式化答案。我只想要一个诚实的上帝帮助，而不是关于"better format my question"的5点评论。如果您需要更多信息，我会很乐意给它。但我没有回答格式化的咸味评论:)
