Extending urllib2.Request, so we can assign HTTP verb manually.

request.py

from urllib2 import Request as RequestBase

class Request(RequestBase):
    def __init__(self, url, data=None, headers=None, origin_req_host=None,
                 unverifiable=False, method=None):
        if headers is None:
            headers = {}
        super(Request, self).__init__(url, data, headers, origin_req_host, unverifiable)
        self.method = method

    def get_method(self):
        if self.method is not None:
            return self.method
        else:
            return super(Request, self).get_method()
