What is the method for connecting Python to Oracle?

The method to connect Python with Oracle can be done using the cx_Oracle module.

Here is an example code in Python that connects to an Oracle database:

import cx_Oracle

# 创建连接
connection = cx_Oracle.connect('username', 'password', 'host:port/service_name')

# 创建游标
cursor = connection.cursor()

# 执行SQL查询
cursor.execute('SELECT * FROM table_name')

# 获取查询结果
result = cursor.fetchall()

# 打印查询结果
for row in result:
    print(row)

# 关闭游标和连接
cursor.close()
connection.close()

Please make sure that you have installed the cx_Oracle module, and replace the placeholders in the sample code with your actual database information and query statement.
