preface
10 wonderful Python libraries, I was stunned after reading!
Let's start happily~
development tool
Python version: 3.6.4
Related modules:
socket module;
textblob module;
pygame module;
pyqrcode module;
pyshorteners module;
Google trans module;
pendulum module;
fabulous module;
pywebview module;
Environment construction
Install Python and add it to the environment variable. pip can install the relevant modules required.
Speedtest (network speed test)
The Speedtest module can test the network bandwidth of the computer.
Use Baidu source installation library.
# Install speedtest pip install speedtest -i https://mirror.baidu.com/pypi/simple/ Copy code
When using, you need to cancel certificate verification
import speedtest
# Global cancel certificate validation
import ssl
ssl._create_default_https_context = ssl._create_unverified_context\
test = speedtest.Speedtest()
down = test.download()
upload = test.upload()
print(f"Upload speed:{round(upload/(1024 * 1024),2)} Mbps")\
print(f"Download speed:{round(down/(1024 * 1024),2)} Mbps")
Copy code
The results are as follows
Upload speed: 31.3 Mbps Download speed: 86.34 Mbps Copy code
Socket (get local ip address)
Using socket, first obtain the host name of the computer, and then obtain the IP address of the computer.
socket is Python's built-in standard library, which does not need to be installed.
import socket as f
hostn = f.gethostname()
Laptop = f.gethostbyname(hostn)
print("Your computer is local IP the address is:" + Laptop)
Copy code
The results are as follows. This IP is the IP in the LAN.
Your computer is local IP The address is: 192.168.2.101 Copy code
If you want to get the public IP address of the computer, you can use some third-party websites, such as the following.
# Browser access, return public IP address https://jsonip.com Copy code
The code is as follows. Also cancel certificate verification.
import json
from urllib.request import urlopen
# Global cancel certificate validation
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("Your computer public network IP the address is:" + ip)
Copy code
Initiate a request for the website and parse the returned results.
Finally, the public IP address is successfully obtained.
# Here's a random one~ Your computer public network IP The address is: 120.236.128.201 Copy code
Textblob (text processing)
TextBlob is a Python library for processing text data, which is only used for English analysis.
Chinese can use SnowNLP, which can easily process Chinese text content. It is inspired by TextBlob.
Now let's do a spell check for English.
from textblob import TextBlob
a = TextBlob("I dream about workin with goof company")
a = a.correct()
print(a)
Copy code
give the result as follows
I dream about working with good company Copy code
You can see that the words in the sentence have been corrected.
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 uses built-in modules to realize complex game logic.
Let's 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()
# click × Code that can close the interface
while 1:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
Copy code
Pyqrcode (generate QR code)
QR code is abbreviated as QR Code(Quick Response Code), which is scientifically called quick response matrix code. It is a kind of two-dimensional bar code. It was invented by Denso Wave company in Japan in 1994.
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.
pyqrcode module is a QR code generator, which is simple to use and written in pure python.
Installation.
# Install pyqrcode pip install pyqrcode -i https://mirror.baidu.com/pypi/simple/ Copy code
Next, baidu click will generate a QR code
import pyqrcode
import png
from pyqrcode import QRCode
inpStr = "www.baidu.com"
qrc = pyqrcode.create(inpStr)
qrc.png("baidu.png", scale=6)
Copy code
Short URLs
Python shorteners is a simple Python library for URL shortening.
18 short chain root domain names are provided for use.
# Install pyshorteners\ pip install pyshorteners -i https://mirror.baidu.com/pypi/simple/ Copy code
With Clck Ru format as an example
import pyshorteners as psn url = "http://www.shuhai.com/" u = psn.Shortener().clckru.short(url) print(u) Copy code
The results are as follows
# result https://clck.ru/WPJgg Copy code
Google trans (translation)
Google Trans is a free and unlimited Python Translation Library, which can be used to automatically detect language types, translations and so on.
Install version 3.1.0a0. The latest version cannot be used.
# Install Google trans pip install googletrans==3.1.0a0 -i https://mirror.baidu.com/pypi/simple/ Copy code
View all supported languages.
import googletrans from googletrans import Translator print(googletrans.LANGUAGES) Copy code
The results are as follows. There are two kinds of Chinese, simplified and traditional.
