Bitcoin core on osx and bitcoinlib socket error

I have some problem about my study..

When I make python file about bitcoinlib like it

from bitcoin.rpc import RawProxy

p = RawProxy()

info = p.getblockchaininfo()

print(info['blocks'])

But it shows me some error like

>> python3 rpc_example.py
Traceback (most recent call last):

    info = p.getblockchaininfo()

ConnectionRefusedError... this is my bitcoin.conf file

alertnotify=myemailscript.sh "Alert: %s"
server=1
rpcuser=bitcoinrpc
rpcpassword=any_long_random_password
txindex=1
testnet=1
daemon=1

When I start -testnet, I can execute some API like getblockchaininfo or getblockhash like

bitcoin-cli getblockchaininfo

  },

}

But I can't execute on python... Please help me TT

I solved it !!

I did not check my bitcoin.conf about testnet When I add some comments in my bitcoin.conf

alertnotify=myemailscript.sh "Alert: %s"
server=1
rpcuser=bitcoinrpc
rpcpassword=any_long_random_password
txindex=1
testnet=1
daemon=1

[testnet]
rpcallowip=*
rpcport=18332

below the [testnet] two line was required.. when you like me Do add this line!! thanks
