An extremely simple example showing you how to write a Redis Client

client.py

import socket


tcp_host = '127.0.0.1'
tcp_port = 6379
tcp_timeout = 10000
buffer_size = 1024

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(tcp_timeout)
s.connect((tcp_host, tcp_port))

# Send a simple get request =>
# r.get("my_key")
msg = "*2\r\n$3\r\nGET\r\n$6\r\nmy_key\r\n"
s.send(msg)
data = s.recv(buffer_size)
print data

# Send a simple pipeline request =>
# r.set("my_key", "HAHA")
# r.get("my_key")
