This document provides client code samples for Python to help you access a database with or without SSL encryption enabled.

Prerequisites

Get the private IPv4 address and port information for database connection in the Network Info section on the Instance Details page in the TencentDB for Redis® console. For detailed directions, see Viewing Instance Details.
Get the account and password for database access. For detailed directions, see Managing Account.
Download and install redis-py. The latest version is recommended.
If you want to connect to the database over SSL, enable SSL encryption to get the SSL certificate file.

Connection Sample Without SSL Encryption Enabled

You need to modify the parameters based on the comments, including IP, port, account, and password for database access.
#!/usr/bin/env python3
#-*- coding: utf-8 -*- 
import redis 

#Replace with the connected instance host and port here 
host = '192.xx.xx.195' 
port = 6379 

#Replace with the instance ID and password here 
user='username' 
pwd='password' 

#When connecting, specify the AUTH information through the `password` parameter. If you connect through the default account, it is `pwd`. If you connect through a custom account, it is `user+'@'+pwd`
r = redis.StrictRedis(host=host, port=port, password=user+'@'+pwd) 

#Database operations can be performed after the connection is established. For more information, visit https://github.com/andymccurdy/redis-py 
r.set('name', 'python_test'); 
print r.get('name')
Execution result:

Connection Sample With SSL Encryption Enabled

You need to modify the parameters based on the comments, including SSL certificate file, IP, port, account, and password for database access.
import redis3 as redis3

if __name__ == "__main__":
#`vip` is the private IPv4 address for database connection, `6379` is the default port number, `pwd` is the password of the default account, and `ca.pem` is the obtained SSL certificate file. You need to replace them as needed.
    client = redis3.Redis(host="vip", port=6379, password="pwd", ssl=True, ssl_cert_reqs="required",
                          ssl_ca_certs="ca.pem")
    print(client.ping())
