Python处理压缩文件的详细指南

import zipfile

# 打开ZIP文件
with zipfile.ZipFile('example.zip', 'r') as zip_ref:
    # 列出ZIP文件中的所有文件
    zip_ref.printdir()

    # 解压ZIP文件中的所有文件
    zip_ref.extractall('extracted_files')

import zipfile

# 创建ZIP文件
with zipfile.ZipFile('new_archive.zip', 'w') as zip_ref:
    # 向ZIP文件中添加文件
    zip_ref.write('file1.txt')
    zip_ref.write('file2.txt')

import zipfile

# 向现有ZIP文件中添加文件
with zipfile.ZipFile('existing_archive.zip', 'a') as zip_ref:
    zip_ref.write('file3.txt')

import tarfile

# 打开TAR文件
with tarfile.open('example.tar', 'r') as tar_ref:
    # 列出TAR文件中的所有文件
    tar_ref.list()

    # 解压TAR文件中的所有文件
    tar_ref.extractall('extracted_files')

import tarfile

# 创建TAR文件
with tarfile.open('new_archive.tar', 'w') as tar_ref:
    # 向TAR文件中添加文件
    tar_ref.add('file1.txt')
    tar_ref.add('file2.txt')

import tarfile

# 向现有TAR文件中添加文件
with tarfile.open('existing_archive.tar', 'a') as tar_ref:
    tar_ref.add('file3.txt')

import shutil

# 创建ZIP文件
shutil.make_archive('archive', 'zip', 'folder_to_compress')

# 创建TAR文件
shutil.make_archive('archive', 'tar', 'folder_to_compress')

import shutil

# 解压ZIP文件
shutil.unpack_archive('archive.zip', 'extracted_files')

# 解压TAR文件
shutil.unpack_archive('archive.tar', 'extracted_files')

import os
import zipfile
from datetime import datetime

def backup_folder(folder_path, backup_path):
    # 获取当前时间，作为备份文件名的一部分
    timestamp = datetime.now().strftime('%Y%m%d%H%M%S')
    backup_file = os.path.join(backup_path, f'backup_{timestamp}.zip')
    
    # 创建ZIP文件
    with zipfile.ZipFile(backup_file, 'w') as zip_ref:
        for foldername, subfolders, filenames in os.walk(folder_path):
            for filename in filenames:
                file_path = os.path.join(foldername, filename)
                zip_ref.write(file_path, os.path.relpath(file_path, folder_path))
    
    print(f'Backup completed: {backup_file}')

​​​​​​​# 使用示例
backup_folder('folder_to_backup', 'backup_directory')

import os
import zipfile

def extract_and_process(zip_file, extract_to):
    # 解压ZIP文件
    with zipfile.ZipFile(zip_file, 'r') as zip_ref:
        zip_ref.extractall(extract_to)
    
    # 处理解压后的文件
    for foldername, subfolders, filenames in os.walk(extract_to):
        for filename in filenames:
            file_path = os.path.join(foldername, filename)
            with open(file_path, 'r') as file:
                print(f'Processing {filename}...')
                content = file.read()

​​​​​​​                print(content)# 使用示例
extract_and_process('example.zip', 'extracted_files')
