使用zstandard在Python中压缩文件

import os
import zstandard as zstd

def compress_file(input_path, output_path):
    # 打开输入文件
    with open(input_path, 'rb') as input_file:
        # 创建压缩器对象
        compressor = zstd.ZstdCompressor()
        
        # 创建输出文件
        with open(output_path, 'wb') as output_file:
            # 压缩并写入输出文件
            compressor.copy_stream(input_file, output_file)
            
    print("File compressed successfully.")

def decompress_file(input_path, output_path):
    # 打开输入文件
    with open(input_path, 'rb') as input_file:
        # 创建解压缩器对象
        decompressor = zstd.ZstdDecompressor()
        
        # 创建输出文件
        with open(output_path, 'wb') as output_file:
            # 解压缩并写入输出文件
            decompressor.copy_stream(input_file, output_file)
            
    print("File decompressed successfully.")

# 压缩文件
compress_file('input.txt', 'compressed.zst')

# 解压缩文件
decompress_file('compressed.zst', 'output.txt')

pip install zstandard
