Program Python3 to check address balance in Bitcoin Core

[xcbtrader]

Hello

I need to make a program in python 3 for check the balance for any bitcoin address.
My idea is use the bitcoin core and check the blockchain stored in my computer.
Is posible?
Could anyone give an example?

Thanks

Bitcoin core does not keep a balance for addresses that are not part of the wallet. You would need to build your own database.

I would recommend executing a getbalance RPC call to your bitcoin-qt client via jgarzik's bitcoinrpc https://github.com/jgarzik/python-bitcoinrpc

I test to check the balance with external service:

http://blockexplorer.com/q/addressbalance/address
https://blockchain.info/es/q/addressbalance/address

I need more links.
Does anyone know any more direction?

Thanks

Blocktrail has an API that can do that.

If you just want to check on blockchain explorer sites, there are quite a few of those:
http://blockr.io/api/v1/address/info/address

Simply parse the JSON data, python 3 has a module for that.

Not sure, if i got you right. There is a bunch of libraries and examples how to access Bitcoin RPC using Python.

Here's an example: http://upcoder.com/7/bitcoin-rpc-from-python

you can setup your own local explorer (ABE) and then check balance ...

This works well enough.
Read up on the bitcoin-cli manual and see what commands you need. It should be pretty straightforwward.

Also make sure you set up your bitcoin.conf with the RPC username and password.

In the end I used Electrum to perform this task in Python 2.7 (Python 3.x does not work).
I put a piece of code as an example:

from electrum import Network
from electrum.util import json_encode, print_msg
import json

n = Network()
n.start()

addr ='1jHyghjyu67ggt56Ggth766ghhjUuggh76gtf5'

h = n.synchronous_get(('blockchain.address.get_balance',[addr]))
print h.get('confirmed')

Thanks
