OZ分享-吉家大宝官方博客: GuessedAtParserWarning: No parser was explicitly specified, so I'm using the best available HTML parser for this system ("html.parser"). This usually isn't a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.
The code that caused this warning is on line 32 of the file D:\PycharmProjects\pythonProject1\11.py. To get rid of this warning, pass the additional argument 'features="html.parser"' to the BeautifulSoup constructor.
soup = BeautifulSoup(html)
简单理解就是把soup = BeautifulSoup(html)改成soup = BeautifulSoup("html.parser")很容易理解
