Python使用PyGreSQL操作PostgreSQL：

import pg

def operate_postgre_tbl_product():
    try:
        #db = pg.connect(dbname = ‘postgres‘, host = ‘192.168.1.200‘, user = ‘postgres‘, passwd = ‘postgres‘)      方法一
        db = pg.connect("host=192.168.1.200 port=5432 dbname=postgres user=postgres")                              方法二
 


    except Exception as  e:
         print (e.args[0])
         return


    sql_desc = "select * from zhang;"
    for row in db.query(sql_desc).dictresult():
        print (row)


    db.close()


if __name__ == ‘__main__‘:
    operate_postgre_tbl_product()

PostgreSQL可以使用psycopg2模塊與Python集成。sycopg2

## 導入psycopg2包
import psycopg2
## 連接到一個給定的數據庫
conn = psycopg2.connect(database="postgres", user="postgres",password="postgres", host="192.168.1.200", port="5432")
## 建立遊標，用來執行數據庫操作
cursor = conn.cursor()

## 執行SQL命令
cursor.execute("CREATE TABLE test_conn(id int, name text)
 
")
cursor.execute("INSERT INTO test_conn values(1,‘haha‘)")

## 提交SQL命令
conn.commit()

## 執行SQL SELECT命令
cursor.execute("select * from test_conn")

## 獲取SELECT返回的元組
rows = cursor.fetchall()
for row in rows:
    print(‘id = ‘,row[0], ‘name = ‘, row[1], ‘\n‘)

## 關閉遊標
cursor.close()

## 關閉數據庫連接
conn.close()
