Question

我对python pgsql库有一个奇怪的“问题”。在我的代码中，我处理错误并打印它，发生它打印2次。

这是代码：

def pg_connect():
    con = None
    try:
        con = psycopg2.connect(database=odoo_array['DBName'], user=odoo_array['User'], password=odoo_array['Password'], host=odoo_array['Host'], port=odoo_array['Port'])
        cur = con.cursor()


    except psycopg2.DatabaseError, e:
        print "["+cur_date()+"] Error: "+str(e)
        sys.exit(1)

    finally:
        if con:
            return cur


def cur_date():
    date = datetime.datetime.now().strftime( "%Y-%m-%d %H:%M:%S" );
    return date

当连接出错时，我想要输出，我得到了这个：

 [2015-08-12 09:09:46] Error: could not connect to server: Connection refused
    Is the server running on host "localhost" and accepting
    TCP/IP connections on port 65432?
 could not connect to server: Connection refused
    Is the server running on host "localhost" and accepting
    TCP/IP connections on port 65432?

无法理解为什么我会错误2次？

Python pgsql错误打印了两倍
