我应该如何使用python脚本将用户名和密码传递给Cassandra

pip install cassandra-driver

from cassandra.cluster import Cluster

# 建立与Cassandra数据库的连接
cluster = Cluster(['<Cassandra节点IP地址>'])
session = cluster.connect()

# 创建一个新的keyspace（可选）
session.execute("CREATE KEYSPACE IF NOT EXISTS my_keyspace WITH replication = {'class':'SimpleStrategy', 'replication_factor':1}")

# 切换到新的keyspace
session.set_keyspace('my_keyspace')

# 创建一个新的表（可选）
session.execute("CREATE TABLE IF NOT EXISTS users (username text PRIMARY KEY, password text)")

# 插入用户名和密码
session.execute("INSERT INTO users (username, password) VALUES (%s, %s)", ('username', 'password'))

# 查询用户名和密码
result = session.execute("SELECT * FROM users WHERE username = %s", ('username',))
for row in result:
    print(row.username, row.password)

# 关闭与Cassandra数据库的连接
session.shutdown()
cluster.shutdown()
