带有 str 和字节码对象的 Python3 错误

Question

所以我尝试编写一个简单的函数来清理文本并对其进行总结：def getTextWaPo(url):page = urllib2.urlopen(url).read().decode('utf8')soup = BeautifulSoup(page, "lxml")text = ' '.join(map(lambda p: p.text, soup.find_all('article')))return text.encode('ascii', errors='replace').replace("?"," ")但是对于这段代码，我收到了这个错误：  File "Autosummarizer.py", line 12, in getTextWaPo  return text.encode('ascii', errors='replace').replace("?"," ")  TypeError: a bytes-like object is required, not 'str'  line 12 ==> text = getTextWaPo(articleURL)我该怎么办？

您必须将最后一行更改     return text.encode('ascii', errors='replace').replace("?"," ")为，     return text.encode('ascii', errors='replace').replace(b"?", b" ")因为在encode()您操作之后bytes，并且必须用其他字节替换字节。
