start = start+2
start = int(start)

end = end-1
end = int(end)
name = s[start:end]

return name

for i in range(0,l-1) :
  id = playlist['items'][i]['pafy'].videoid
  v=pafy.new(id)
  #video = pafy.new('https://www.youtube.com/watch?v='+id)
  print("Video Number : {}".format(i))
  name = extract_name_from_title(v.title)
