python- youtube. Get url video list

I am working with python 2.7. I want to create a txt with the list of videos in a particular youtube list:

example list

I wrote (I'm totally new in Python):

from bs4 import BeautifulSoup
import urllib2
import re 


url='https://www.youtube.com/playlist?list=PLYjSYQBFeM-zQeZFpWeZ_4tnhc3GQWNj8'
page=urllib2.urlopen(url)
soup = BeautifulSoup(page.read())

href_tags = soup.find_all(href=True)

ff = open("C:/exp/file.txt", "w")

and then this worked:

for i in href_tags:
    ff.write(str(i))
ff.close()

But, since I want to keep only those that have "watch" inside, I tried instead:

for i in href_tags:
    if re.findall('watch',str(i))=='watch':
        ff.write(str(i))
ff.close()

But I got an empty txt.

How can I keep only the links? Is there a better way to do this?

Solution

  • A simple in should do:

    for i in href_tags:
    if 'watch' in str(i):
        ff.write(str(i))
    ff.close()
