我创建了一个gui程序，框架可以从一个页面移动到另一个页面，我只在使用方法时才能使用它，但是只要我介绍一个类，我就会得到以下错误：
TypeError: 'Frame' object is not callable
我使用的代码如下：
import sys
from tkinter import *
from tkinter import ttk
class teachingContent(Tk):
def __init__(self):
super(teachingContent, self).__init__()
self.first_title_frame = ttk.Frame()
self.first_frame = ttk.Frame()
def nextButtonPressed(self):
pass
def prevButtonPressed(self):
pass
def formSize(self):
self.geometry("650x450+200+200") # Sets the size of the gui
self.title("Python Tutor")
self.nbutton = Button(text = "Next", command = self.nextButtonPressed).place(x=561,y=418)
self.pbutton = Button(text = "Previous", command = self.prevButtonPressed).place(x=0,y=418)
title_height = 40
self.first_title_frame(self, height=title_height, bg = 'black')
self.first_title_frame['borderwidth'] = 2
self.first_title_frame.grid(column=0, row=0, padx=35, pady=5, sticky=(W, N, E))
self.first_frame(self, bg = 'DarkSlateGray4')
self.first_frame['borderwidth'] = 2
self.first_frame['relief'] = 'sunken'
self.first_frame.grid(column=0, row=0, padx=33, pady=50, sticky=(W, N, E))
self.label = Label(self.first_title_frame, text = "Welcome to the Tutor").pack()
self.label = Label(self.first_frame, text = "Welcome to the Python Tutor. In this program you will learn to tools and techniques need to use Python.")
self.label.grid(column=0, row=0, ipadx=85,pady=11, padx=11, sticky=(N))
tc = teachingContent()
tc.formSize()
我对此行中的代码进行了更改，添加.configure，如下所示：
self.first_title_frame.configure(self, height=title_height, bg = 'black')
但这给了我以下追溯：
Traceback (most recent call last):
File "C:\Users\Tete De Bite\Dropbox\Year3\FinalYearProject\pythonTutoringSystem\debug.py", line 47, in <module>
tc.formSize()
File "C:\Users\Tete De Bite\Dropbox\Year3\FinalYearProject\pythonTutoringSystem\debug.py", line 31, in formSize
self.first_title_frame.configure(self, height=title_height, bg = 'black')
File "C:\Python33\lib\tkinter\__init__.py", line 1263, in configure
return self._configure('configure', cnf, kw)
File "C:\Python33\lib\tkinter\__init__.py", line 1254, in _configure
self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
_tkinter.TclError: unknown option "-pady"
有没有人有任何想法可以纠正我正在制作的编程错误？
