Python Learning Essentials: 10 wonderful Python libraries. I was stunned after reading them


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
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 =
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:
 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
 Copy code

The code is as follows, and the certificate verification is also cancelled.

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'') as fp:
    content =

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:
 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.

Let's do a spell check for English.

from textblob import TextBlob

a = TextBlob("I dream about workin with goof company")
a = a.correct()
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 a graphics and sound library 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"

#Click × Code that can close the interface
while 1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
Copy code


Pyqrcode (generate QR code)

QR code is abbreviated as QR Code(Quick Response Code), scientific name is quick response matrix code, which is a kind of two-dimensional bar code. It was invented by Denso Wave company of 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.


#Install pyqrcode
pip install pyqrcode -i
Copy code

Next, baidu click will generate a QR code

import pyqrcode
import png
from pyqrcode import QRCode

inpStr = ""
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.


#Installing pyshorteners\
pip install pyshorteners -i
Copy code

In Clck Ru format as an example

import pyshorteners as psn

url = ""
u = psn.Shortener().clckru.short(url)
Copy code

The results are as follows

 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
Copy code

View all supported languages.

import googletrans
from googletrans import Translator

Copy code

Copy code
translater = Translator()
out = translater.translate("Hello", dest='en', src='auto')
Copy code


give the result as follows

#Translation results
Translated(src=zh-CN, dest=en, text=Hello, pronunciation=None, extra_data="{'translat...")
Copy code

Fabulous (add text color)

If you run a Python program on the command line, the output is the same color, which is inconvenient to observe

With Fabulous, you can add images and colored text to highlight the output


#Installing fabulous
pip install fabulous -i
Copy code

Let's take a look at an example!

from fabulous.color import bold, magenta, highlight_red
