新人求助,BeautifulSoup库未写明解析器警告,这个问题该如何解决

一运行就显示这样,

GuessedAtParserWarning: No parser was explicitly specified, so I'm using the best available HTML parser for this system ("lxml"). 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 15 of the file E:/PycharmProjects/爬电影.py. To get rid of this warning, pass the additional argument 'features="lxml"' to the BeautifulSoup constructor.

  bf = BeautifulSoup(html)
[]

 

翻译:guseedataparserwarning:没有显式地指定解析器,因此我使用这个系统的最佳可用HTML解析器(“lxml”)。这通常不是问题,但是如果您在另一个系统上或在不同的虚拟环境中运行此代码,则它可能使用不同的解析器,并且行为也不同。
导致此警告的代码位于文件E:/PycharmProjects/爬影.py的第15行。若要消除此警告,请将附加参数“features=”lxml“传递给BeautifulSoup构造函数。

 

 

本人萌新一枚,想请教大佬如何将附加参数“features=”lxml“传递给BeautifulSoup构造函数。代码怎么改造呢?
