官方文档 - https://docs.python.org/3/library/urllib.html

urllib is a package that collects several modules for working with URLs:

• urllib.request for opening and reading URLs
• urllib.error containing the exceptions raised by urllib.request
• urllib.parse for parsing URLs
• urllib.robotparser for parsing robots.txt files

urllib.request

urllib.request.urlopen(url,data=None,[timeout, ],cafile=None,capath=None,cadefault=False,context=None)

urllib.parse

1. urljoin

from urllib.parse import urljoin

url = 'https://chenxuefan.cn'
url = urljoin(url, 'note')  # 'https://chenxuefan.cn/note'

2. quote

from urllib.parse import quote, unquote

ch = '老鼠人'
en = quote(ch)  # '%E8%80%81%E9%BC%A0%E4%BA%BA'
ch = unquote(en)  # '老鼠人'
