Python使用zlib对数据进行简单压

import zlib
import this


def main():
    python_zen = this.s  # 获取Python之禅的Unicode字符串
    com_bytes = zlib.compress(python_zen.encode('utf-8'))  # 编码为UTF-8格式的字节进行压缩
    print(com_bytes)
    decom_bytes = zlib.decompress(com_bytes)  # 将压缩的字节进行解压缩
    print(decom_bytes.decode('utf-8'))  # 将解压缩的字节进行UTF-8解码得到Unicode字符串


if __name__ == '__main__':
    main()

import this
import zlib


def main():
    python_zen = this.s  # 获取字符
    with open('data.txt', 'wb') as f:  # 使用文件写入的上下文环境
        f.write(python_zen.encode('utf-8'))  # 写入未压缩的字节数据

    with open('com_data.txt', 'wb') as f:  # 使用文件写入上下文环境
        com_zen = zlib.compress(python_zen.encode('utf-8'))  # 将字符串编码并压缩
        f.write(com_zen)  # 写入压缩后的字节数据


if __name__ == '__main__':
    main()

The Zen of Python, by Tim Peters

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!
