To redirect a post and pass on the post data with Python Django, we can redirect with HttpResponseRedirect.
For instance, we write
def some_view(request):
    #do some stuff
    request.session['_old_post'] = request.POST
    return HttpResponseRedirect('next_view')
def next_view(request):
    old_post = request.session.get('_old_post')
    #do some stuff using old_post
to create 2 views some_view and next_view.
In some_view, we return the HttpResponseRedirect response to redirect to next_view.
And in next_view we get the _old_post value from request.session that we saved in some_view.
And then we do stuff with the value.
