【问题描述】:
import bs4 as bs
import urllib.request
import re
import os
from colorama import Fore, Back, Style, init
init()
def highlight(word):
if word in keywords:
return Fore.RED + str(word) + Fore.RESET
else:
return str(word)
for newurl in newurls:
url = urllib.request.urlopen(newurl)
soup1 = bs.BeautifulSoup(url, 'lxml')
paragraphs =soup1.findAll('p')
print (Fore.GREEN + soup1.h2.text + Fore.RESET)
print('')
for paragraph in paragraphs:
if paragraph != None:
textpara = paragraph.text.strip().split(' ')
colored_words = list(map(highlight, textpara))
print(" ".join(colored_words).encode("utf-8")) #encode("utf-8")
else:
pass
我将列出要查看的关键词和网址。 在 url 中运行几个关键字后,我得到这样的输出
b'\x1b[31mthe desired \x1b[31mmystery corners \x1b[31mthe differential .
\x1b[31mthe back \x1b[31mpretends to be \x1b[31mthe'
我删除了 encode("utf-8") 并且出现编码错误

return codecs.charmap_encode(input,self.errors,encoding_map)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\u2019' in

我哪里错了?
【问题讨论】:
-
更改编码,不要删除!
-
除了 encode("utf-8") 之外我还能使用什么其他编码
