python中zipfile、tarfile压缩文件模块的使用

ZipFile 压缩单个文件

import zipfile
import os

with zipfile.ZipFile('log.zip', 'w') as z:
    z.write('log.log')

解压文件

with zipfile.ZipFile('log.zip', 'r') as z:
    print(z.namelist())     # 查看压缩包中的文件列表
    print(z.read(z.namelist()[0]))  # 读出来压缩包中的第一个文件的内容打印到屏幕，也可保存到文件中
    # z.extractall('aaa')      # 解压，可设置解压路径
    # z.extract('log.log')      # 解压，可选择解压某个文件
    z.extractall()      # 解压全部

压缩某个目录下所有文件

def compress_file(zipfilename, dirname):      # zipfilename是压缩包名字，dirname是要打包的目录
    if os.path.isfile(dirname):
        with zipfile.ZipFile(zipfilename, 'w') as z:
            z.write(dirname)
    else:
        with zipfile.ZipFile(zipfilename, 'w') as z:
            for root, dirs, files in os.walk(dirname):
                for single_file in files:
                    if single_file != zipfilename:
                        filepath = os.path.join(root, single_file)
                        z.write(filepath)

compress_file('a.zip', '.')      # 执行函数

添加文件到已有的zip包中

def addfile(zipfilename, dirname):
    if os.path.isfile(dirname):
        with zipfile.ZipFile(zipfilename, 'a') as z:
            z.write(dirname)
    else:
        with zipfile.ZipFile(zipfilename, 'a') as z:
            for root, dirs, files in os.walk(dirname):
                for single_file in files:
                    if single_file != zipfilename:
                        filepath = os.path.join(root, single_file)
                        z.write(filepath)

addfile('a.zip', 'test.txt')

查看压缩包中的文件

def viewfile(zipfilename):
    with zipfile.ZipFile(zipfilename, 'r') as z:
        print(z.namelist())

viewfile('a.zip')

**TarFile** 压缩文件 ``` import tarfile import os

with tarfile.open('a.tar', 'w') as tar: tar.add('log.log', arcname='log.log') tar.add('test.txt', arcname='test.txt')

解压文件

with tarfile.open('a.tar', 'r') as tar: print(tar.getmembers()) # 查看压缩包内文件成员 # tar.extract('test.txt') # 可选择解压某个文件 # tar.extractall('ccc') # 可设置解压路径 tar.extractall() # 解压全部

压缩某个目录下所有文件

def compress_file(tarfilename, dirname): # tarfilename是压缩包名字，dirname是要打包的目录 if os.path.isfile(dirname): with tarfile.open(tarfilename, 'w') as tar: tar.add(dirname) else: with tarfile.open(tarfilename, 'w') as tar: for root, dirs, files in os.walk(dirname): for single_file in files: # if single_file != tarfilename: filepath = os.path.join(root, single_file) tar.add(filepath)

compress_file('test.tar', 'test.txt') compress_file('t.tar', '.')

添加文件到已有的tar包中

def addfile(tarfilename, dirname): # tarfilename是压缩包名字，dirname是要打包的目录 if os.path.isfile(dirname): with tarfile.open(tarfilename, 'a') as tar: tar.add(dirname) else: with tarfile.open(tarfilename, 'a') as tar: for root, dirs, files in os.walk(dirname): for single_file in files: # if single_file != tarfilename: filepath = os.path.join(root, single_file) tar.add(filepath)

addfile('t.tar', 'ttt.txt') addfile('t.tar', 'ttt')
