    1. 使用連線符: +

    world = "World"print "Hello " + world + " ! "

    2. 使用佔位符來內插

    world = "World"print "Hello %s !" % world

    3. 使用函式

    li = ["my","name","is","bob"]mystr = " ".join(li)print mystr

    上面的語句中字串是作為引數傳入的,可以直接用變數替換:

    begin_date = "2012-04-06 00:00:00"end_date = "2012-04-06 23:59:59"select * from usb where time between to_date(begin_date,"YYYY-MM-DD HH24:MI:SS") and to_date(end_date,"YYYY-MM-DD HH24:MI:SS")
