python - "bound method": How to create a file name in sub directory with python

Question

我尝试在子目录中创建具有随机名称的文件，但出现此错误:

 URL/<bound method webSiteCompanies.nameGenerator of
 <__main__.webSiteCompanies instance at 0x7fc30dbccd88>>

我的代码看起来像这样:

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

import os
import string
import random


class webSiteCompanies():

    def __init__(self):
        self.path = "URL"
        self.stringSize = 42

    def nameGenerator(self):
        chars = string.ascii_uppercase + string.digits
        return str(''.join(random.choice(chars) for _ in range(self.stringSize)))


    def createFile(self):
        realPath = self.path + "/" + str(self.nameGenerator)
        try:
            os.mkdir(self.path)
        except Exception:
            pass

        print realPath
        os.mknod(realPath+".txt")

# Main
if __name__=='__main__':
    bob = webSiteCompanies()
    bob.createFile()

我的文件已创建，但名称错误...

如何解决我的问题？

Answer 1

您需要调用函数 - self.nameGenerator() 。示例-

realPath = self.path + "/" + str(self.nameGenerator())
