how to post multiple value with same key in python requests?
Question:

but,is not working,how to post `football` and `basketball` in `interests`
field?


Answer: Dictionary keys _must_ be unique, you can't repeat them. You'd use a sequence
of key-value tuples instead, and pass this to `data`:

    
    
    requests.post(url, data=[('interests', 'football'), ('interests', 'basketball')])
    

Demo POST to <http://httpbin.org>:

    
    
    >>> import requests
    >>> url = 'http://httpbin.org/post'
    >>> r = requests.post(url, data=[('interests', 'football'), ('interests', 'basketball')])
    >>> r.json()['form']
    {u'interests': [u'football', u'basketball']}
