写的一段python老是报错 求解 老是在*cur*的地方报错

Posted 2023-05-17

def addNewFlight(): addFlightNumber = input("Please input a new flight's number:") cur.execute("SELECT FlightNumber From FlightInformation") rows=cur.fetchall() for i in range(0,len(rows)): if addFlightNumber == "%s"%rows[i]: print "The flight number has existed, not need to be added " break else: addStart = input("Please input this flight's starting point:") addTerminal = input("Please input this flight's terminal point:") addDepartureTime = input("Please input this flight's departure time:") addArrivalTime = input("Please input this flight's arrival time:") addFares = int(raw_input("Please input this flight's fares:")) addRemainingTickets = int(raw_input("Please input this flight's remaining tickets:") *cur*.execute("insert into FlightInformation values(%s, %s, %s, %s, %s, %s, %s)" %(addFlightNumber, addStart, addTerminal, addDepartureTime, addArrivalTime, addFares, addRemainingTickets) print "Add new flight successful, now, the new flight's specific information is : " cur.execute("select from FlightInformation where IDNumber=%s",userIDNumber) rows = cur.fetchall() for row in rows: print row[0] break conn.commit()

cur变量你没有赋值就用了啊，数据库如果是mysql的话，应该这样吧：

db = MySQLdb.connect("localhost","root","123456","myciti" )
cur = db.cursor()

参考技术A 建议你发一个python文件的附件。这样那些大牛可以直接 下载运行一下。追问

诶？还可以加附件的？？

追答

还真不能，以前提问还没注意，这个很基本的功能居然不能实现。

参考技术B 亲，报错的提示，你也给出来嘛追问

就是跳出一个框：There‘s an error in your program：invalid syntax
然后就跳回去

追答

晕，你语法出错了
*cur*，有这种写法，是说看到这么怪异

追问

没有那两个*
那是我写来做记号的

追答

你这个贴出来的代码，排版全乱了，我现在只能怀疑你 ‘缩进’ 是不是有问题
你截个图嘛

配置Android SDK Manager.exe,老是出现这种错误提示而继续不下去，该怎么弄啊？求解啊，各位大侠

参考技术A GOOGLE 的连接不正常吧，多试几次吧，我国的墙很厉害的
