Python，urllib2 模块中的 NameError，但仅在少数网站中

Question

website = raw_input('website: ')
with open('words.txt', 'r+') as arquivo:
    for lendo in arquivo.readlines():
        msmwebsite = website + lendo
        try:
            abrindo = urllib2.urlopen(msmwebsite)
            abrindo2 = abrindo.read()           

        except URLError as e:
            pass

        if abrindo.code == 200:
            palavras = ['registration', 'there is no form']
            for palavras2 in palavras:
                if palavras2 in abrindo2:
                    print msmwebsite, 'up'

                else:
                    pass

        else:
            pass

它正在工作，但出于某种原因，我在某些网站上遇到了这个错误:

if abrindo.code == 200:
NameError: name 'abrindo' is not defined

Answer 1

将 pass 替换为 continue。至少做一些错误记录，因为你默默地跳过错误的链接。

如果您的请求导致 URLError，则没有定义变量 abrindo，因此您的错误。
