Question: How do i get the raw txid to broadcast to jsonRPC using "eth_sendRawTransaction" method

[araa47]

My code:

from ethereum import transactions
from ethereum import utils
import requests 
import json 


def json_rpc(url, method, params, id):
		headers = {'content-type': 'application/json'}
		payload = {
			"method": method,
			"params": params,
			"jsonrpc": "2.0",
			"id": id,
		}
		try:
			response = requests.post(url, data=json.dumps(payload), headers=headers)
			if response.status_code == 200:
				response = response.json()
				return response
		except Exception as e:
			print(e)
			return(e)





tx = transactions.Transaction(nonce=8, gasprice=5000000000, 
    startgas=45000, to=contract_address, value=0, 


data="0x957a0e210000000000000000000000000000000000000000000000000000000000000037").sign(private_key)
tx = tx.to_dict()
print(tx)

Output:

 {'nonce': 8, 'gasprice': 5000000000, 'startgas': 45000, 'to': '0x4d21f3618bc4c50475d4b30993d80cffe78b3650', 'value': 0, 'data': '0x3078393537613065323130303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303337', 'v': 27, 'r': 104827557381449577376519412355902868429829733841563149787296871707166833642558, 's': 29002009444020075645692529433910482836532514345220494513395292371410739844134, 'sender': '0xd1bb5d5c362bb4faf25c23b3c7c42c8ea30dc10d', 'hash': '0x20d1a85cf3e6f4d11655c9ba0f09602ea4881b6abcc192581fca18b24634cd2c'}

Question:

The geth json RPC api has a method called "eth_sendRawTransaction" which requires one param. How do I encode the above output to send correctly using json rpc to my geth node? Which value am I supposed to send?
