Question

在Windows 7上使用Python 3。

import pickle
import os.path
from tkinter import * # Import tkinter
import tkinter.messagebox   

class Places:
  def __init__(self, name, street, city, state, zip):
    self.name = name
    self.street = street
    self.city = city
    self.state = state
    self.zip = zip

class PlacesBook:
  def __init__(self):      
    window = Tk() # Create a window
    window.title("PlacesBook") # Set title

我收到错误builtins.NameError：name＆＃39; self＆＃39;未定义在＆＃34;类PlacesBook：＆＃34;

问题出在你的缩进上，在Python中，缩进是非常重要的，这就是你如何定义代码的哪一部分在类，方法中......

如果你做python 3，另一点你所有的类都必须从object继承。

import pickle
import os.path
from tkinter import * # Import tkinter
import tkinter.messagebox

class Places(object):
    def __init__(self, name, street, city, state, zip):
        self.name = name
        self.street = street
        self.city = city
        self.state = state
        self.zip = zip

class PlacesBook(object):
    def __init__(self):
        window = Tk() # Create a window
        window.title("PlacesBook") # Set title

builtins.NameError：未定义名称“self”
