Python 連接數據庫

# 導入pymysql模塊
import pymysql
# 連接database
conn = pymysql.connect(host="localhost",port=3306, user="root",password="root",database="Python",charset="utf8")
# 得到一個可以執行SQL語句的光標對象
cursor = conn.cursor()
# 定義要執行的SQL語句
sql = "select * from PY_USER"
# 執行SQL語句
cursor.execute(sql)
results = cursor.fetchall()

for i in results:
    print(list(i))
# 關閉光標對象
cursor.close()
# 關閉數據庫連接
conn.close()
