未使用beautifulsoup4定义的名称错误'html'

我的python 3.4.4代码是：

import urllib.request
from bs4 import BeautifulSoup
from html.parser import HTMLParser

urls = 'file:///C:/Users/tarunuday/Documents/scrapdata/mech.html'
htmlfile = urllib.request.urlopen(urls)
soup = BeautifulSoup(htmlfile,html.parser)

我收到这个错误

Traceback (most recent call last):
    File "C:\Python34\saved\scrapping\scrapping2.py", line 7, in <module>
    soup = BeautifulSoup(htmlfile,html.parser)
    NameError: name 'html' is not defined

现在我知道HTMLParser是py2.x，而html.parser是py3.x，但是如何使它工作呢？该BS4网站说If you get the ImportError “No module named html.parser”, your problem is that you’re running the Python 3 version of the code under Python 2.，但我跑3.x和我得到一个NameError不是一个ImportError
