Automatic file upload?

Question

Python

Good afternoon!
Task: Download a file at a specified time and location.
Conditions: There is a website and direct links to the file. You need to download this file twice every day.
Difficulty: Every day the file name changes "2015-04-29_10-59.mp4" -> "2015-04-30_10-59.mp4" etc.
The file address also changes " http://***/2015-04-29/ " -> http://***/2015-04-30/ "(Accordingly, only the date changes, which, as I understand it, can be taken from systems.)
What I can do: I'm learning python but haven't figured out how to do it yet.Are there ready-made programs for these tasks or what method is more appropriate to use in this situation?

Answer 1

Requests you need.
Well, datetime.

from datetime import datetime
import requests

now = datetime.now().strftime('%Y-%m-%d_%H-%M')
string_that_you_need = now + '.mp4'  # Сейчас это выглядит, как "2015-04-29_10-59.mp4"
request = requests.get('http://site.that/you/need/%s' % string_that_you_need)
f = open('file.mp4', 'wb')
f.write(request.content)
f.close()

Answer 2

The current date into a string in the required format, this string into the right places in the URL, and, in general, that's all.

Answer 3

If you have Linux or something similar, then the usual bash is enough:

#!/bin/sh
now="$(date +'%Y-%m-%d')"
url="http://example.com/$now/$now.mp4"
wget -c -P /папка/куда/сохранять/ $url

And put it in your daily cron.
Look at the wget options, there are a lot of different things, such as retry on error, downloading a directory / the entire site, etc.
