In the Jianghu , It has been circulating about Python The legend of ——Python omnipotent , Besides having children .
Python To have such a good name , Not only because of their own superiority , What's more, they can't do without the omnipotent libraries behind them .
today , Just let us know 5 paragraph Python library , See how they work in different fields ~
Pillow yes PIL（Python Graphics library ） A branch of . For users ,Pillow More friendly , Through it, you can create thumbnails , Converting between file formats 、 rotate 、 Application filter , Display images, etc .
If you want to do Batch image processing , Pillow Is a necessary library .
stay Pillow In the library , There are more than twenty modules , It also supports many plug-ins . The most common one is Image Module with the same name Image class , Many other modules are in Image Based on the module, the image is further processed .
from PIL import Image
im = Image.open("picture.jpg")
new_im = im.convert("L")
print(new_im.mode)
new_im.show()
PyTorch It's based on Torch Of Python Open source machine learning library , For natural language processing applications .
It is mainly composed of Facebook The AI team developed , Not only can you achieve powerful GPU Speed up , It also supports dynamic neural networks , This is now many mainstream frameworks, such as TensorFlow Not supported .
PyTorch Provides Two advanced features ：
1. With powerful GPU Accelerated tensor computation ;
2. A deep neural network with an automatic derivation system , except Facebook outside ,Twitter、GMU and Salesforce And other institutions have adopted PyTorch.
One “ Rich and colorful ” Module ——Python Of Colorama modular . It can span multiple terminals , Display different colors and backgrounds of Fonts , Just import colorama The module can , You don't have to look like linux Same color designation .
Fore： Used to change the color of the output text ;
Style： Used to change the brightness of the output text ;
Back： Used to change the background of the output text .
Colorama Support 8 Color ： black （black）、 Red （red）、 green （green）、 yellow （yellow）、 Blue （blue）、 Magenta （magenta）、 Cyan （cyan）、 white （white）.
from colorama import Fore, Back, Style
print(Fore.RED + 'some red text')
print(Back.GREEN + 'and with a green background')
print(Style.DIM + 'and in dim text')
print(Style.RESET_ALL)
print('back to normal now')
