Example Analysis of pyquery initialization in python

This article mainly introduces the example analysis of pyquery initialization in python, which is very detailed and has certain reference value. Friends who are interested must finish it!

1. Introduce PyQuery and alias it as pq. The long HTML string is then declared and passed as a parameter to PyQuery.

Html = 'first itemsecond itemthird itemfourth itemfifth item'''from pyquery import PyQuery as pqdoc = pq (html) print (doc (' li'))

2. When URL is passed into the web page, you only need to specify the url parameter.

From pyquery import PyQuery as pqdoc = pq (url=' http://cuiqingcai.com')print(doc('title'))

3. Transfer the local file name and specify the parameter as filename.

From pyquery import PyQuery as pqdoc = pq (filename='demo.html') print (doc ('li'))

Here you need the local HTML file demo.html, which is the HTML string to be analyzed. This reads the contents of the local file and then passes it to PyQuery as a string.
