Python study notes 15: Chinese encoding conversion in URL

When doing crawlers, sometimes you need to crawl and write Chinese content. However, Chinese characters will be converted to URL characters in the form of %xx in some cases.

such as:

%E7%BE%8E%E5%A5%B3

The above code means "beauty".

The urllib library of Python3 can encode and decode Chinese URLs.

import urllib.parse

cn = input("请输入中文：")
bfb = urllib.parse.quote(cn)   # 转为 url 编码
print( bfb )
print( urllib.parse.unquote(bfb) )  # 解码
