Hello everyone, I'm Xiao F~
Python has a lot of cool third-party libraries that make the task easier.
Today I will share with you 10 interesting Python libraries, each of which is very useful!
They are speedtest, socket, textblob, pygame, pyqrcode, pyshorteners, googletrans, pendulum, fabulous, pywebview.
Let me introduce to you below~
① speedtest (Internet speed test)
The Speedtest module can test the network bandwidth of the computer.
Use Baidu source to install the library.
# 安装speedtest
pip install speedtest -i https://mirror.baidu.com/pypi/simple/
When used, certificate verification needs to be canceled.
import speedtest
# 全局取消证书验证
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
test = speedtest.Speedtest()
down = test.download()
upload = test.upload()
print(f"上传速度：{round(upload/(1024 * 1024),2)} Mbps")
print(f"下载速度：{round(down/(1024 * 1024),2)} Mbps")
The results obtained are as follows.
上传速度：31.3 Mbps
下载速度：86.34 Mbps
It seems that Xiao F's Internet speed is quite fast.
② socket (get the local ip address)
Using socket, first obtain the host name of the computer, and then obtain the IP address of the machine.
Among them, socket is a built-in standard library of Python, which does not need to be installed.
import socket as f
hostn = f.gethostname()
Laptop = f.gethostbyname(hostn)
print("你的电脑本地IP地址是：" + Laptop)
The result is as follows, this IP is the IP in the LAN .
你的电脑本地IP地址是：192.168.2.101
If you want to get the public IP address of your computer , you can use some third-party websites, such as the one below.
# 浏览器访问, 返回公网IP地址
https://jsonip.com
The code is as follows, which also cancels the certificate verification.
import json
from urllib.request import urlopen
# 全局取消证书验证
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
with urlopen(r'https://jsonip.com') as fp:
content = fp.read().decode()
ip = json.loads(content)['ip']
print("你的电脑公网IP地址是：" + ip)
Make a request to the website and parse the returned result.
Finally, the public IP address was successfully obtained.
# 这里随便写了一个~
你的电脑公网IP地址是：120.236.128.201
③ textblob (text processing)
TextBlob is a Python library for working with textual data, for English analysis only.
Chinese can use SnowNLP , which can easily process Chinese text content, which is inspired by TextBlob.
Let's do a spell check in English.
from textblob import TextBlob
a = TextBlob("I dream about workin with goof company")
a = a.correct()
print(a)
The results are as follows.
I dream about working with good company
As you can see, the words in the sentence have been corrected.
④ pygame (making games)
pygame, a Python library for making games.
It not only provides developers with graphics and sound libraries for making games, but also can use built-in modules to implement complex game logic.
Below we use pygame to make a small music player.
from pygame import mixer
import pygame
import sys
pygame.display.set_mode([300, 300])
music = "my_dream.mp3"
mixer.init()
mixer.music.load(music)
mixer.music.play()
# 点击×可以关闭界面的代码
while 1:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
Run the above code and the computer will play music.
You must add a graphical interface to pygame, otherwise there will be no sound.
⑤ pyqrcode (generate QR code)
QR Code (Quick Response Code) for short, scientifically called Quick Response Matrix Code, is a type of 2D barcode. Invented in 1994 by Denso Wave in Japan.
Now with the popularity of smart phones, they have been widely used in daily life, such as commodity information query, social friend interaction, network address access and so on.
The pyqrcode module is a QR code generator that is simple to use and written in pure python.
Install.
# 安装pyqrcode
pip install pyqrcode -i https://mirror.baidu.com/pypi/simple/
The following will generate a QR code from "Baidu".
import pyqrcode
import png
from pyqrcode import QRCode
inpStr = "www.baidu.com"
qrc = pyqrcode.create(inpStr)
qrc.png("baidu.png", scale=6)
The QR code picture is as follows.
WeChat scans out text content, which is Baidu’s website, so it should be something to do with it.
Scan with the browser of the mobile phone, you can jump to the web page normally.
Use documentation:
https://pythonhosted.org/PyQRCode/
⑥ pyshorteners (short URL)
pyshorteners is a simple URL shortening Python library.
18 short-chain root domain names are provided for use.
Install.
# 安装pyshorteners
pip install pyshorteners -i https://mirror.baidu.com/pypi/simple/
Take the clck.ru format as an example.
import pyshorteners as psn
url = "http://www.shuhai.com/"
u = psn.Shortener().clckru.short(url)
print(u)
The results obtained are as follows.
# 结果
https://clck.ru/WPJgg
can be accessed normally.
Use documentation:
https://pyshorteners.readthedocs.io/en/latest/
⑦ googletrans (translation)
Googletrans is a free and unlimited Python translation library that can be used to automatically detect language types, translations, and more.
Install version 3.1.0a0, the latest version cannot be used.
# 安装googletrans
pip install googletrans==3.1.0a0 -i https://mirror.baidu.com/pypi/simple/
View all supported languages.
import googletrans
from googletrans import Translator
print(googletrans.LANGUAGES)
The results are as follows, in which there are two types of Chinese, Simplified and Traditional.
