get url from crosspost via praw with python

how do I get the target submission from a crosspost?

(actually I don't need the submission itself, only the video it may refer to)

Minimum example, that should work, but doesn't

import praw
reddit = praw.Reddit(...)
s = reddit.submission('84vepy')
s2 = reddit.submission(url=s.url)
print s2.url

result: 

>>> print s2.url
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/praw/models/reddit/base.py", line 31, in __getattr__
    self._fetch()
  File "/usr/local/lib/python2.7/dist-packages/praw/models/reddit/submission.py", line 149, in _fetch
    'sort': self.comment_sort})
  File "/usr/local/lib/python2.7/dist-packages/praw/reddit.py", line 367, in get
    data = self.request('GET', path, params=params)
  File "/usr/local/lib/python2.7/dist-packages/praw/reddit.py", line 472, in request
    params=params)
  File "/usr/local/lib/python2.7/dist-packages/prawcore/sessions.py", line 181, in request
    params=params, url=url)
  File "/usr/local/lib/python2.7/dist-packages/prawcore/sessions.py", line 126, in _request_with_retries
    raise self.STATUS_EXCEPTIONS[response.status_code](response)
prawcore.exceptions.NotFound: received 404 HTTP response

I think the problem here, is that s.url is https://v.redd.it/5wtgcop6g4m01[1]', which is apparently no valid input for reddit.submission. But I don't know how to convert that url to a valid submission.

You can get the cross post with s.crosspost_parent.

thanks it works.

for anyone, who finds this and has the same problem, you get original submission with: 

s2=reddit.submission(s.crosspost_parent.split('_')[1])

(the split is required, because crosspost_parent gives the fullname, but the constructors wants just the id. By convention the id is the part after the first underscore)
