从webscrape输出中删除'u [英] Remove 'u from a webscrape output

问题描述

您好，我使用Beautifulsoup解析了一个网站并获得了一个名称作为输出.但是运行脚本后，我得到了 [u'word1'，u'word2'，u'word3'] 输出.我正在寻找的是'word1 word2 word3'.如何摆脱这个 u'并将结果变成单个字符串?

Hi ' im using Beautifulsoup to parse a website and get a name as output. But after running the script, i get a [u'word1', u'word2', u'word3'] output. What i'm looking for is 'word1 word2 word3'. how do get rid of this u' and make the result a single string?

from bs4 import BeautifulSoup
import urllib2
import re

myfile = open("base/dogs.txt","w+")
myfile.close()

url="http://trackinfo.com/entries-race.jsp?raceid=GBR$20140302A01"
page=urllib2.urlopen(url)
soup = BeautifulSoup(page.read())
names=soup.findAll('a',{'href':re.compile("dog")})
myfile = open("base/dogs.txt","w+")
for eachname in names:
    d = (str(eachname.string.split()))+"\n"
    print [x.encode('ascii') for x in d]
    myfile.write(d)

myfile.close()

推荐答案

使用 .encode()给出的答案是给您您所需要的，但可能不是您所需要的.您可以保留unicode编码，而不用表示事物的编码或类型的方式表示事物.因此，它们仍会成为 [u'word1'，u'word2'，u'word3'] -避免破坏对无法支持的语言的支持以ASCII表示-但是打印为 word1 word2 word3 .

The answers here using .encode() are giving you what you ask for, but probably not what you need. You can keep the unicode encoding and not represent things in a way that shows you what their encoding or type is. Thus, they'll still be [u'word1', u'word2', u'word3'] -- which avoids breaking support for languages that can't be represented in ASCII -- but printed as word1 word2 word3.

只需:

for eachname in names:
    d = ' '.join(eachname.string.split()) + '\n'
    print d
    myfile.write(d)
