字节换算

def bytes_conversion(number):
    symbols = ('K', 'M', 'G', 'T', 'P', 'E', 'Z', 'Y')
    prefix = dict()
    for i, s in enumerate(symbols):
        prefix[s] = 1 << (i + 1) * 10
    for s in reversed(symbols):
        if int(number) >= prefix[s]:
            value = float(number) / prefix[s]
            return '%.2f%s' % (value, s)
        return "%sB" % number

随机密码生成

import random
import string
a=string.ascii_letters+string.digits
key=[]
def getKey():
	key=random.sample(a,8)
	keys="".join(key)
	return keys
for i in range(1000):
	print(getKey())

用Windows文件资源管理器打开文件并选中

import os, pathlib
file = r'D:/Users/Haujet/Desktop/1.png'
os.system(f'explorer /select, "{pathlib.Path(file)}')
