Question

我正在尝试为我用python编写的twitter抓取程序制作UI。我包含了代码，并对所有建议持开放态度。

import random
from Tkinter import Tk, Label, Button, Entry, StringVar, DISABLED, NORMAL, END, W, E

class MyFirstGUI:
    def __init__(self, master):
        self.master = master
        master.title("Python Scraper")

        self.label = Label(master, text="Please enter a hashtag (#hashtag) to search twitter for.")
        self.label1.pack()

        #Box to input hashtag

        self.label2 = Label(master, text = "How many results would you like per search? Recommended: 200-1000.")
        self.label2.pack()

        #Box to enter results per search

        self.label3= Label(master, text = "How many times would you like Twitter scraped? Warning: do not exceed the data cap! Recommended 6 or less times")
        self.label3.pack()

        #box to enter number of times to scrape twitter

        self.label4 = Label(master, text = "What would you like on your x-axis?")
        self.label4.pack()

        #drop down box with the 5 options

        self.label5 = Label(master, text = "What would you like on your y-axis")
        self.label5.pack()

        #dropdown box with the same five options as above

        self.search_button = Button(master, text="Search", command=self.search)
        #self.search_button.pack()



    def search(self):

    #This should take the inputs from the boxes and selections from the x and y axis and 
    #enter it into another program that will be pasted below. I don't want to share due to 
    #OAuth credentials etc..
        print("Greetings!")

root = Tk()
my_gui = MyFirstGUI(root)
root.mainloop()

我在运行时遇到此错误：

Traceback (most recent call last):
  File "tkkkk2.py", line 32, in <module>
    my_gui = MyFirstGUI(root)
  File "tkkkk2.py", line 10, in __init__
    self.label1.pack()
AttributeError: MyFirstGUI instance has no attribute 'label1'

我认为发生了什么：我认为我需要对标签做些什么。我觉得tkinter默认处理一个标签就好了，但是我需要做一些事来制作另一个标签。

下：我不知道如何制作输入框或将这些值传递给另一个功能。我正在运行El Capitan的macbook air，我有python 2.7。

这看起来很简单。你有这两行：

self.label = Label(master, text="Please enter a hashtag (#hashtag) to search twitter for.")
self.label1.pack()

我认为第一行应该是这样的：

self.label1 = Label(master, text="Please enter a hashtag (#hashtag) to search twitter for.")

我们在哪里制作self.label - ＆gt; self.label1

在Tkinter中制作UI。遇到问题
