Python implements a dictionary of search Youdao

because I want to test English four, so I get up early in the morning by the English words, but as the dregs of English, I can only be on the Web page to look up the meaning of the word. Check more, heart tired, then think how to look at the terminal under the word, so the speed is not fast?

Now, I look closely at each query, the URL in the browser address bar changes, found each time the browser submitted the URL is "http://www.youdao.com/w/eng/" xxxxx "/#keyfrom =dict2.index" ( One of the XXXXX represents the word to look for), with this discovery, then we download the URL point to the page, and then extract the information we need to do it?

Emmmm, this job is the most appropriate thing to do with Python.

Basic steps: Import the requests module and the RE module, first download the URL address to the webpage, and then use Python's powerful regular expression to extract the translated information of the word. Because I want to translate between English and Chinese, I have written two pieces of code, the first one is Chinese to English, the second is English translation.

OK, let's take a look at the effect:

Emmmm,ok, after sending the blog to continue to recite the word "sad " "sad" "sad"
