Python乾貨項目:【新聞急先鋒】新聞API獲取谷歌頭條新聞

新聞API是用於搜索和檢索來自整個Web的實時新聞文章，可以根據某些標準檢索新聞。

使用它，可以獲取任何新聞網站上運行的頂級新聞，也可以搜索特定主題(或關鍵字)的頂級新聞。

假設要搜索的主題(關鍵字)是「geeksabiek」，或者可能與某個特定的頻道有關。所有這些都可以完成，但是需要API密鑰才能開始。

以下是上述想法的實施情況：

# importing requests package

import requests

def NewsFromBBC():

# BBC news api

main_url = " https://newsapi.org/v1/articles?source=bbc-news&sortBy=top&apiKey=4dbc17e007ab436fb66416009dfb59a8"

# fetching data in json format

open_bbc_page = requests.get(main_url).json()

# getting all articles in a string article

article = open_bbc_page["articles"]

# empty list which will

# contain all trending news

results = []

for ar in article:

results.append(ar["title"])

for i in range(len(results)):

# printing all trending news

print(i + 1, results[i])

#to read the news out loud for us

from win32com.client import Dispatch

speak = Dispatch("SAPI.Spvoice")

speak.Speak(results)

# Driver Code

if __name__ == '__main__':

# function call

NewsFromBBC()

產出：

案例：GoogleNewsFeed

先決條件——Python tkinter

在本文中，我們將編寫一個python腳本，從GoogleNewsFeed中提取新聞文章用Gnewsclient模塊，把它綁在一起a GUI申請。Gnewsclient是GoogleNewsFeed的python客戶端。為了使用這個API，必須先顯式地安裝這個API。

安裝

下面的終端命令安裝gnewsclient包及其所有必需的庫。運行就行了。

pip install gnewsclient

使用模塊

導入gnewsclient模塊

創建NewsClient對象並設置當前參數設置

獲取新聞信息

Python 3# import module

from gnewsclient import gnewsclient

# declare a NewsClient object

client = gnewsclient.NewsClient(language='hindi', location='india', topic='Business', max_results=5)

# get news feed

client.get_news()

產出：

下面的代碼描述了如何從本模塊收集的信息中列印其他因素，如位置、語言和主題：

Python 3import gnewsclient

from gnewsclient import gnewsclient

client = gnewsclient.NewsClient(language='hindi',

location='india',

topic='Business',

max_results=5)

# prints location

print("Location: \n",client.locations)

print()

# prints languages

print("Language \n",client.languages)

print()

# prints topics

print("Topic \n",client.topics)

產出：

案例：Python 3from gnewsclient import gnewsclient

client = gnewsclient.NewsClient(language='english',

location='india',

topic='sports',

max_results=3)

news_list = client.get_news()

for item in news_list:

print("Title : ", item['title'])

print("Link : ", item['link'])

print("")

產出：

程序2該代碼在GUI中實現了程序1的方法。

Python 3# import modules

from tkinter import *

from gnewsclient import gnewsclient

# defined funtions

def news():

client = gnewsclient.NewsClient(

language=lang.get(), location=loc.get(), topic=top.get(), max_results=3)

news_list = client.get_news()

result_title.set(news_list[0]["title"] + "\n" +

news_list[1]["title"] + "\n" + news_list[2]["title"])

# tkinter object

master = Tk()

master.title("NEWS")

# background set to grey

master.configure(bg='light grey')

# Variable Classes in tkinter

result_title = StringVar()

result_link = StringVar()

# Creating label for each information

# name using widget Label

Label(master, text="Choose language :", bg="light grey").grid(row=0, sticky=W)

Label(master, text="Choose Location :", bg="light grey").grid(row=1, sticky=W)

Label(master, text="Choose Topic :", bg="light grey").grid(row=2, sticky=W)

lang = Entry(master)

lang.grid(row=0, column=1)

loc = Entry(master)

loc.grid(row=1, column=1)

top = Entry(master)

top.grid(row=2, column=1)

# Creating lebel for class variable

# name using widget Entry

Label(master, text="", textvariable=result_title,

bg="light grey").grid(row=3, column=1, sticky=W)

# creating a button using the widget

# Button to call the submit function

Button(master, text="SHOW", command=news, bg="white").grid(row=1, column=3)

mainloop()
