"""A user-created :class:`Request <Request>` object.
Used to prepare a :class:`PreparedRequest <PreparedRequest>`, which is sent to the server.
:param method: HTTP method to use.
:param url: URL to send.
:param headers: dictionary of headers to send.
:param files: dictionary of {filename: fileobject} files to multipart upload.
:param data: the body to attach to the request. If a dictionary or
list of tuples ``[(key, value)]`` is provided, form-encoding will
take place.
:param json: json for the body to attach to the request (if files or data is not specified).
:param params: URL parameters to append to the URL. If a dictionary or
list of tuples ``[(key, value)]`` is provided, form-encoding will
take place.
:param auth: Auth handler or (user, pass) tuple.
:param cookies: dictionary or CookieJar of cookies to attach to this request.
:param hooks: dictionary of callback hooks, for internal usage.
Usage::
>>> import requests
