Python--常用第三方模块

Python常用第三方模块

Windows用管理员打开py shell

1.Pillow

安装Pillow

pip install pillow

缩放图片

from PIL import Image
im = Image.open('test.jpg')

w, h = im.size

im.thumbnail((w//2, h//2))

im.save('thumbnail.jpg', 'jpeg')

模糊图片

from PIL import Image, ImageFilter

im = Image.open('test.jpg')

im2 = im.filter(ImageFilter.BLUR)
Im2.save('blur.jpg', 'jpeg')

绘制验证码

from PIL import Image, ImageDraw, ImageFont, ImageFilter
import random
def randChar():
    return chr(random.randint(65,90))
def randColor():
    return (random.randint(64, 255), random.randint(64, 255), random.randint(64, 255))
def randColor2():
    return (random.randint(32, 127), random.randint(32, 127), random.randint(32, 127))
width = 60 *4
height = 60
image = Image.new('RGB', (width, height), (255, 255, 255))
font = ImageFont.truetype('c://windows/fonts/Arial.ttf', 36)
draw = ImageDraw.Draw(image)
for x in range(width):
    for y in range(height):
        draw.point((x, y), fill=rndColor())

for t in range(4):
    draw.text((60 * t + 10, 10), rndChar(), font=font, fill=rndColor2())
image = image.filter(ImageFilter.BLUR)
image.save('code.jpg', 'jpeg')

2.request

安装request

pip install request

使用request

通过GET访问一个页面，只需要几行代码：

import requests
r = requests.get('https://www.baidu.com/')
r.status_code
r.text

对于带参数的URL，传入一个dict作为parameter参数

留坑。。。

3.chardet

与字符串编码相关

安装chardet

pip install chardet

使用chardet

检测编码 chardet.detect(b'Hello, world!')

data = '离离原上草，一岁一枯荣'.encode('gbk')
chardet.detect(data)

data = '离离原上草，一岁一枯荣'.encode('utf-8')
chardet.detect(data)

data = '最新の主要ニュース'.encode('euc-jp')
chardet.detect(data)

chardet支持检测的编码列表官方文档
