Python百分号编码和哈希摘要

Python 百分号编码、解码

from urllib.parse import quote, unquote

name = "王者荣耀"
print(quote(name)) # %E7%8E%8B%E8%80%85%E8%8D%A3%E8%80%80

print(unquote("%E7%8E%8B%E8%80%85%E8%8D%A3%E8%80%80")) # 王者荣耀

Python哈希摘要

from hashlib import md5, sha256

hasher = md5('123456'.encode())
print(hasher.hexdigest())

# 文件生成 哈希摘要
with open("a.txt", "rb") as file:
    hasher = md5(file.read())
    print(hasher.hexdigest())
    
hasher = md5()
with open("a.txt", "rb") as file:
    # 使用迭代器读取文件，避免文件一次性加载到内存
    file_iter = iter(lambda: file.read(512), b'')
    for data in file_iter:
        hasher.update(data)
    print(hasher.hexdigest())
