Web scraping beginners tried to make a command to get the movie name of next Friday Road Show

1. Overview

It's a hassle to check the TV section every time what the movie of this Friday Road Show is. So, I wondered if I could get the movie name of the Friday Road Show from the terminal of the PC with one command using Python web scraping.

2. Goal

--Display the title of the movie that will be broadcast next Friday with a single command on the terminal. --At that time, scrape the Friday Road Show lineup page (https://kinro.jointv.jp/lineup) using Python's Beautiful Soup. .. Let's look at the structure of the page to be scraped in advance.

Friday Road Show website

3. Code

kinro.py


#coding:utf-8

import urllib.request
import datetime
from bs4 import BeautifulSoup


def func():
	html = urllib.request.urlopen("https://kinro.jointv.jp/lineup")
	soup = BeautifulSoup(html, "lxml")
	today = datetime.date.today()
	nextFriday = today + datetime.timedelta(days = (4 - today.weekday()) % 7)
	strnextFriday = nextFriday.strftime("%Y%m%d")
	a = soup.find_all("a", href = "/lineup/" + strnextFriday)
	tmp = a[0].find("img")
	title = tmp.attrs['alt']
	print(title)

if __name__ == '__main__':
    func()

Open a terminal and in the same directory as this code,

$python kinro.py

Execute the command

Detective Conan: A Pure Black Nightmare#Within April 14, 2017
Cinderella#April 15, 2017~21st

If the title of the movie is displayed like, it is successful.

Of course, in .barhrc

alias kinro='python ~/my_dir/kinro.py'  #Directory name matches environment

If you define this command like this, you can get the movie name of next Friday Road Show with one command of $ kinro on any directory.
