DESCRIPTION
    Requests HTTP Library
    ~~~~~~~~~~~~~~~~~~~~~
    
    Requests is an HTTP library, written in Python, for human beings. Basic GET
    usage:
    
       >>> import requests
       >>> r = requests.get(‘https://www.python.org‘)
       >>> r.status_code
       
 
200
       >>> ‘Python is a programming language‘ in r.content
       True
    
    ... or POST:
    
       >>> payload = dict(key1=‘value1‘, key2=‘value2‘)
       >>> r = requests.post(‘http://httpbin.org/post‘, data=payload)
       >>> print(r.text)
       {
         ...
         
 
"form": {
           "key2": "value2",
           "key1": "value1"
         },
         ...
       }
    
    The other HTTP methods are supported - see `requests.api`. Full documentation
    is at <http://python-requests.org>.
