I develop simple dapp where uses python as backend for interaction with geth over jsonrpc
My user-story is
1. I call json rpc method eth_compileSolidity for compilation
2. I call json rpc method eth_sendTransaction for transfer contract into blockchain, and get back contract ABI
3. And then, i want call method in my contract
In AlethZero, when i create contract, i see something like this
19c54359… :method 1
412f2e82… :method 2
And after that, i send transaction with data:
$0x19c54359 - method id
arg1
arg2
What i should use in pyethereum for method call?

abi = json.loads(self.contract_abi)
for i, entity in enumerate(abi):
if entity['type'] == 'constructor': # Current impelementation of ABI don't understand solidity constructor
del(abi[i])
raw = json.dumps(abi)
translator = ContractTranslator(raw.encode("ascii"))
bytes_pres = translator.encode("sensors", [1])
res = binascii.hexlify(bytes_pres)
result = json_rpc.call(self.contract_addr[2:], res.decode("ascii"))
