今天在pip安裝BeautifulSoup4的時候,出現(xiàn)了"Could not find a version that satisfies the requirement beauifulSoup4 (from versions: ) No matching distribution found for beauifulSoup4"
原因:BeautifulSoup4已經(jīng)集成到了bs4
使用的時候變成: import bs4
soup =bs4.BeautifulSoup(html_cont,'html.parser',from_encoding='utf-8')
原因:BeautifulSoup4已經(jīng)集成到了bs4
使用的時候變成: import bs4
soup =bs4.BeautifulSoup(html_cont,'html.parser',from_encoding='utf-8')

url?=?"https://wwww.baidu.com/" response?=?request.urlopen(url) print(response.getcode()) print(response.read()) 應(yīng)該用urlopen方法 request.Request是構(gòu)建一個完整的請求: ????req?=?urllib.request.Request(url) ????response?...

說實(shí)話,一大堆錯誤,一大堆未定義變量跟無法導(dǎo)入的變量(urlli3,getcode,Rquest,urlopen,cookielib,build_opener,install_opener,urlopen),更可恨的是,utf-8指定了依然報錯,搞毛喔
