在tkinter中的Pprint

Question

我在試圖找到一種方法來顯示我正在爲GUI工作的谷歌搜索/ RSS FEED的標題，網址和時間戳列表。我遇到很多麻煩，試圖找到一種將結果以可讀形式排序的方法。任何文章或指導，至於做什麼將不勝感激！

from tkinter import * 
import urllib.request 
import feedparser 
from pprint import pprint 



search_term = ('') #search term for url 
quoted_search_term = urllib.parse.quote(search_term) 
def go(): 
    text.delete(1.0, END) #delete text 
    rss_string = 'https://news.google.com/news/section?output=rss'.format  (quoted_search_term) 
    parsed_rss_string = feedparser.parse(rss_string) #assigning variable for parsed feed 
    text.insert(1.0, parsed_rss_string) #insert text of parsed feed 


browser_window = Tk() #tk window 
browser_window.title('RSS Feed') #Window title 
label = Label(browser_window, text= 'Search:') 
entry = Entry(browser_window) 
button = Button(browser_window, text='Go', command = go)#Go Button 
text = Text(browser_window) #results box 

label.pack(side=TOP) #Positioning of search title 
entry.pack(side=TOP) #Positioning of search box 
button.pack(side=TOP)#Positioning of go 
text.pack(side= RIGHT) #Positioning of text 
browser_window.mainloop()

爲了美化串，使用pprint.pformat：

from pprint import pformat 

... 

def go(): 
    ... 
    parsed = feedparser.parse(rss_string) 
    prettified = pformat(parsed) 
    text.insert("1.0", prettified) 

注：

• 有一個在URL https://news.google.com/news/section?output=rss沒有佔位符;沒有影響str.format。
• feedparser.parse不返回字符串，而是字典。

UPDATE顯示發佈日期，標題，網址，而你需要從字典中獲得這些條目：

def go(): 
    rss_string = 'https://news.google.com/news/section?output=rss' 
    parsed = feedparser.parse(rss_string) 
    text.delete("1.0", END) 
    for entry in parsed['entries']: 
     text.insert(END, '{0[published]} - {0[title]} {0[link]}\n\n'.format(entry))
