Question

from tkinter import * 
import json
import requests 


accessToken = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx'
query = r'xxxxxxx/?fields=posts.limit(20)'

window = Tk()
window.title('The Sakht Launday')
pagePicture = PhotoImage(file= 'pagePicture.GIF')
Label (window, image = pagePicture).grid(row = 0, column = 0, sticky = 'E')

#Text To Display Inside
listbox = Text(window, width = 50, height = 25, wrap = WORD, background ='White').grid(row = 0, column = 1)

reQ = requests.get('https://graph.facebook.com/v3.1/' + query, {'access_token': accessToken})
tempData = reQ.json()
json.dumps(tempData)
data = tempData['posts']['data']
for results in data:
    caption = results['message']
    timeUploaded = results['created_time']
    urlID = results['id']
    finalPost = 'Caption: {0}\nTime Uploaded: {1}\nURL: {2}\n\n'.format(caption, timeUploaded, urlID)
    listbox.insert(0, finalPost)

我相信您已经知道我要在这里做什么。我使用facebook graph api解析了数据，现在我想在GUI应用程序的列表框或消息框中打印该数据，但是每次运行此应用程序时，我都会得到

PATH，错误：第27行，在 listbox.insert（0，finalPost） AttributeError：“ NoneType”对象没有属性“插入”

Answer 1

几何管理器grid返回None：

替换：

listbox = Text(window, width = 50, height = 25, wrap = WORD, background ='White').grid(row = 0, column = 1)

具有：

listbox = Text(window, width = 50, height = 25, wrap = WORD, background ='White')
listbox.grid(row = 0, column = 1)

Tkinter：AttributeError：'NoneType'对象没有属性'insert'
