python爬虫之BeautifulSoup初始运行时警告

1、Python在进行网页爬虫时，代码如下：from urllib.request import urlopen from bs4 import BeautifulSoup html = urlopen("http://www.pythonscraping.com/pages/page1.html") bsObj = BeautifulSoup(html) print (bsObj.h1) nameList = bsObj.findAll(text='the prince') print(len(nameList))

3、紧接着是因此此警告的原因，初始化时，未加上解析器亿姣灵秀类型The code that caused this warning is on line 4 of the file C:/Users/15057/PycharmProjects/Stock/Stockinvest/test.py. To get rid of this warning, change code that looks like this:BeautifulSoup(YOUR_MARKUP})to this:BeautifulSoup(YOUR_MARKUP, "lxml") markup_type=markup_type)

5、将代码bsObj = BeautifulSoup(html.read())改为bsObj = BeautifulSoup(html.read(),"lxml")就不会报错了
