Python Requests and persistent sessions
Question: I am using the [requests](http://docs.python-requests.org/en/latest/) module
(version 0.10.0 with Python 2.5). I have figured out how to submit data to a
login form on a website and retrieve the session key, but I can't see an
obvious way to use this session key in subsequent requests. Can someone fill
in the ellipsis in the code below or suggest another approach?

    
    
    >>> import requests
    >>> login_data =  {'formPosted':'1', 'login_email':'me@example.com', 'password':'pw'}
    >>> r = requests.post('https://localhost/login.py', login_data)
    >>> 
    >>> r.text
    u'You are being redirected <a href="profilePage?_ck=1349394964">here</a>'
    >>> r.cookies
    {'session_id_myapp': '127-0-0-1-825ff22a-6ed1-453b-aebc-5d3cf2987065'}
    >>> 
    >>> r2 = requests.get('https://localhost/profile_data.json', ...)
    


Answer: You can easily create a persistent session using:

    
    
    s = requests.session()
    

After that, continue with your requests as you would:

    
    
    s.post('https://localhost/login.py', login_data)
    #logged in! cookies saved for future requests.
    r2 = s.get('https://localhost/profile_data.json', ...)
    #cookies sent automatically!
    #do whatever, s will keep your cookies intact :)
