jsonsocket
This is a small Python library for sending data over sockets.
It allows sending lists, dictionaries, strings, etc. It can handle very large data (I've tested it with 10GB of data). Any JSON-serializable data is accepted.
Examples:
from jsonsocket import Client, Server
host = 'localhost'
port = '8000'
# Client code:
client = Client()
client.connect(host, port).send({'some_list': [123, 456]})
response = client.recv()
# response now is {'data': {'some_list': [123, 456]}}
client.close()
# Server code:
server = Server(host, port)
server.accept()
data = server.recv()
# data now is: {'some_list': [123, 456]}
server.send({'data': data}).close()
