在Python3中流式传输压缩文件

import gzip

def compress_file(input_file, output_file):
    with open(input_file, 'rb') as f_in:
        with gzip.open(output_file, 'wb') as f_out:
            f_out.writelines(f_in)

def decompress_file(input_file, output_file):
    with gzip.open(input_file, 'rb') as f_in:
        with open(output_file, 'wb') as f_out:
            f_out.writelines(f_in)

# 示例用法
input_file = 'input.txt'
compressed_file = 'compressed.gz'
decompressed_file = 'decompressed.txt'

# 压缩文件
compress_file(input_file, compressed_file)

# 解压缩文件
decompress_file(compressed_file, decompressed_file)
