beautifulsoup python download file code example
Example: how to download the links that i find with beatifulsoap
import requests
from bs4 import BeautifulSoup
'''
URL of the archive web-page which provides link to
all video lectures. It would have been tiring to
download each video manually.
In this example, we first crawl the webpage to extract
all the links and then download videos.
'''
# specify the URL of the archive here
archive_url = "http://www-personal.umich.edu/~csev/books/py4inf/media/"
def get_video_links():
#create response object
r = requests.get(archive_url)
#create beautiful-soup object
soup = BeautifulSoup(r.content,'html5lib')
#find all links on web-page
links = soup.findAll('a')
#filter the link sending with .mp4
video_links = [archive_url + link['href'] for link in links if link['href'].endswith('mp4')]
return video_links
def download_video_series(video_links):
for link in video_links:
'''
iterate through all links in video_links
and download them one by one
'''
#obtain filename by splitting url and getting last string
file_name = link.split('/')[-1]
print "Downloading file:%s"%file_name
#create response object
r = requests.get(link, stream = True)
#download started
with open(file_name, 'wb') as f:
for chunk in r.iter_content(chunk_size = 1024*1024):
if chunk:
f.write(chunk)
print "%s downloaded!\n"%file_name
print "All videos downloaded!"
return

#getting all video links
video_links = get_video_links()
#download all videos
