Python AttributeError實例沒有屬性，當我添加一個新的方法。

Question

我想我的類中調用的另一種方法，由於某種原因，我收到AttributeError的：portfinder實例沒有屬性「generatePortNumber」見下面我的代碼：

，當我試着撥打generatePortNumber我得到相同的錯誤。我從來沒有遇到過這個問題。

#!/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()
