Modules Introduction

Rich

Rich 是一款提供終端機介面中 豐富的 文字效果及精美的格式設定的 Python 函式庫。 Rich API 讓終端機介面加上色彩及樣式變得易如反掌。Rich 也可以繪製漂亮的表格、進度條、Markdown、語法醒目標示的程式碼、Traceback（追溯）……。

Pretty Errors

Pretty Errors 能將錯誤訊息美化，使開發者更好的追蹤錯誤

pretty-errors-features

Requests

Requests 是一個簡單且優雅的HTTP模組

>>> import requests
>>> r = requests.get('https://httpbin.org/basic-auth/user/pass', auth=('user', 'pass'))
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=utf8'
>>> r.encoding
'utf-8'
>>> r.text
'{"authenticated": true, ...'
>>> r.json()
{'authenticated': True, ...}

Pycord

Pycord 是一個基於 discord.py 編寫的 Discord 機器人模組

import discord

bot = discord.Bot()

@bot.slash_command()
async def hello(ctx, name: str = None):
    name = name or ctx.author.name
    await ctx.respond(f"Hello {name}!")

@bot.user_command(name="Say Hello")
async def hi(ctx, user):
    await ctx.respond(f"{ctx.author.mention} says hello to {user.name}!")

bot.run("token")

Pipx

Pipx 將模組安裝於虛擬環境，使其可以在安裝多個包時不衝突

pipx-features

PDM

PDM 用於管理與整合虛擬環境，讓同個Python版本可以安裝多個模組並互相不衝突

Beautiful Soup 4

Beautiful Soup 是一個可以從HTML或XML文件中提取數據的Python庫。 它能夠透過你喜歡的轉換器實現慣用的文件導航、查找、修改文件的方式。

>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(html_doc, 'html.parser')
>>> 
>>> html_doc = """
... <html><head><title>The Dormouse's story</title></head>
... <body>
... <p class="title"><b>The Dormouse's story</b></p>
... 
... <p class="story">Once upon a time there were three little sisters; and their names were
... <a href="http://example.com/elsie" class="sister" id="link1">Elsie</a>,

... and they lived at the bottom of a well.</p>
... 
... <p class="story">...</p>
... """
>>> 
>>> soup.title
'<title>The Dormouse\'s story</title>'
>>> 
>>> soup.title.name

>>> 
>>> soup.find_all('a')
['<a class="sister" href="http://example.com/elsie" id="link1">Elsie</a>',
 '<a class="sister" href="http://example.com/lacie" id="link2">Lacie</a>',
 '<a class="sister" href="http://example.com/tillie" id="link3">Tillie</a>']
>>> 
>>> soup.find(id="link3")
'<a class="sister" href="http://example.com/tillie" id="link3">Tillie</a>/
