Question

我正在尝试在我的类中调用另一个方法，由于某种原因我得到了AttributeError：portfinder实例没有属性'generatePortNumber'请参阅下面的代码：

当我试图调用generatePortNumber时，我得到了同样的错误。我从未遇到过这个问题。

#!/usr/bin/python
# -*- coding: utf-8 -*-

import sqlite3 as lite
import sys
import random



class portfinder:
    """docstring for ClassName"""
    def __init__(self):
        self.portsToCheck = ['agentport','BatchProcessingAgentPort','databaseport','indexserviceport','monitorport','servicefacadeport','webdriverport']
        self.dataBasePort = (u'60025',)
        self.portInUse = False 
        self.x = 0



    def generatePortNumber(self):
            self.newPortNumber = random.randrange(8000, 9000)
            print self.newPortNumber
            return self.newPortNumber

    def findUsedPortsinDB(self):
        con = lite.connect('D:\play\Opes\db.sqlite3')
        with con:    
            cur = con.cursor()
            sqlStatement = "Select " + self.portsToCheck[2] +' From Jobs_jobs'
            print sqlStatement
            cur.execute(sqlStatement)
            rows = cur.fetchall()
            for row in rows:
                print row 
                if row == self.dataBasePort:
                    self.portInUse = "true"
                    self.generatePortNumber()                   





if __name__ == "__main__":
    m = portfinder()
    m.findUsedPortsinDB()

Answer 1

发现我的方法中有一个额外缩进的错误

Python AttributeError实例没有属性，当我添加一个新方法时。
