安装嬴图Python驱动并部署一个嬴图实例后，就可以将应用于数据库连接了。

你可以使用UltipaConfig类的配置建立一个连接，点击查看UltipaConfig参数。

建立连接

使用Connection类的NewConnection方法创建连接：

from ultipa import Connection, UltipaConfig

ultipaConfig = UltipaConfig()
# URI example: ultipaConfig.hosts = ["https://mqj4zouys.us-east-1.cloud.ultipa.com:60010"]
ultipaConfig.hosts = ["192.168.1.85:60061", "192.168.1.87:60061", "192.168.1.88:60061"]
ultipaConfig.username = "<username>"
ultipaConfig.password = "<password>"

Conn = Connection.NewConnection(defaultConfig=ultipaConfig)

# Tests the connection: The connection is successfully established if the code is 0
response = Conn.test()
print("Code =", response.status.code)

Code = 0

使用配置文件

本例演示如何使用配置文件.env建立连接：

import os
from pathlib import Path
from dotenv import dotenv_values, load_dotenv
from ultipa import Connection, UltipaConfig

# Loads the .env file and overrides system environment variables
env_path = Path('./.env')
env_dict = dotenv_values(dotenv_path=env_path)
load_dotenv(encoding='utf-8', override=True)

hosts = os.getenv("hosts").split(",")
username = os.getenv("username")
password = os.getenv("password")

ultipaConfig = UltipaConfig(hosts=hosts, username=username, password=password, heartBeat=10)
Conn = Connection.NewConnection(defaultConfig=ultipaConfig)

response = Conn.test()
# The connection is successfully established if the code is 0
print("Code =", response.status.code)

Code = 0

.env文件示例：

#hosts=https://mqj4zouys.us-east-1.cloud.ultipa.com:60010
hosts=192.168.1.85:60061,192.168.1.86:60061,192.168.1.87:60061
username=<username>
password=<password>
passwordEncrypt=PasswordEncrypt.MD5
defaultGraph=miniCircle
#crt=F:\\ultipa.crt
#maxRecvSize=10240
