Basic GET usage: >>> import requests >>> r = requests.get('https://www.python.org') >>> r.status_code 200 >>> b'Python is a programming language' in r.content True ... or POST: >>> payload = dict(key1='value1', key2='value2') >>> r = requests.post('https://httpbin.org/post', data=payload) >>> print(r.text) { ... "form": { "key1": "value1", "key2": "value2" }, ... } The other HTTP methods are supported - see `requests.api`.
