Python文件不会下载

Question

这是我的代码，所有的URL都在一个配置解析器格式的文件中。当按下按钮时，文件将不会下载。出了什么问题？我用了urllib我应该用urllib2吗？有些函数可能在那里，但没有使用只是忽略了这一点。你知道吗

import wx
import ConfigParser
import urllib

def Download(url):
    response = urllib.urlopen(url).read()
    doned = wx.MessageDialog("Download Done")
    doned.ShowModal()
    doned.Destroy()

#First thing i gona do is Parse 98 box data

            e6392g = True
            print e6392g,"639 go"
        else:

G = wx.App(False)

G.MainLoop()

但在函数Download(url)将不起作用，它将不下载

def Download(url):
        response = urllib.urlopen(url).read()
        doned = wx.MessageDialog("Download Done")
        doned.ShowModal()
        doned.Destroy()

触发Download(url)的是一些if和elsif语句

                print e6602g,"660 go"
            else:

Answer 1

What did go wrong? I used urllib should I have used urllib2?

是的。只需在代码中添加2就可以解决问题，这一事实显然证明了这一点，但并不能解释太多。你知道吗

正如^{}的文档所说：

Deprecated since version 2.6: The urlopen() function has been removed in Python 3 in favor of urllib2.urlopen().

这并不意味着他们从2.6开始就停止修复urllib中的bug（直到2.7.9才有bug修复），但这确实意味着永远不会添加缺少的功能。其中包括一些类型的HTTP身份验证、重定向、带有非标准CAs的HTTPS、代理设置和代理身份验证。你知道吗

除了“下载没有发生”或者您试图下载的URL（您似乎传入了一个名为Update_box的变量，该变量没有分配到任何地方）或者您正在运行的安装程序之外，如果不知道任何问题，就不可能确切地知道这些问题中的哪一个（或任何其他问题）是关键。你知道吗
