Python之zipfile模块的使用，zipfile怎么读,1、判断是否是zip

1、判断是否是zip文件

#!/usr/bin/env python3# encoding: utf-8import zipfilefilenames = [‘tcp_server.py‘, ‘test.py‘, ‘test.zip‘]for filename in filenames:    print(‘{:>15}  {}‘.format(filename, zipfile.is_zipfile(filename)))

zipfile_is_zipfile.py

运行效果

[[email protected] mnt]# python3 zipfile_is_zipfile.py   tcp_server.py  False        test.py  False       test.zip  True

2、查看zip里面的文件名

#!/usr/bin/env python3# encoding: utf-8import zipfilewith zipfile.ZipFile(‘test.zip‘, ‘r‘) as zf:    print(zf.namelist())

zipfile_namelist.py

运行效果

[[email protected] mnt]# python3 zipfile_namelist.py [‘tcp_client.py‘, ‘tcp_server.py‘, ‘test.py‘]

3、查看zip里面文件的大小、文件名、修改时间等参数

#!/usr/bin/env python3# encoding: utf-8import zipfileimport datetimedef print_info(archive_name):    with zipfile.ZipFile(archive_name) as zf:        for info in zf.infolist():            print(info.filename)            print(‘   Comment    :‘, info.comment)            mod_date = datetime.datetime(*info.date_time)            print(‘   Modified    :‘, mod_date)            if info.create_system == 0:                system = ‘Windows‘            elif info.create_system == 3:                system = ‘Unix‘            else:                system = ‘UNKNOWN‘            print(‘   System    :‘, system)            print(‘   Zip Version    :‘, info.create_version)            print(‘   Compressed    :‘, info.compress_size, ‘bytes‘)            print(‘   UnCompressed    :‘, info.file_size, ‘bytes‘)if __name__ == ‘__main__‘:    print_info(‘test.zip‘)

zipfile_infolist.py

运行效果

[[email protected] mnt]# python3 zipfile_infolist.py tcp_client.py   Comment    : b‘‘   Modified    : 2020-01-09 18:01:58   System    : Windows   Zip Version    : 63   Compressed    : 221 bytes   UnCompressed    : 301 bytestcp_server.py   Comment    : b‘‘   Modified    : 2020-01-09 18:15:06   System    : Windows   Zip Version    : 63   Compressed    : 511 bytes   UnCompressed    : 996 bytestest.py   Comment    : b‘‘   Modified    : 2020-01-09 16:58:52   System    : Windows   Zip Version    : 63   Compressed    : 206 bytes   UnCompressed    : 426 bytes

4、指定文件名查看zip里面的文件信息

#!/usr/bin/env python3# encoding: utf-8import zipfilewith zipfile.ZipFile(‘test.zip‘) as zf:    filenames = [‘test.py‘, ‘README.txt‘]    for filename in filenames:        try:            info = zf.getinfo(filename)        except KeyError:            print(‘文件：{},不存在zip里面‘.format(filename))        else:            print(‘文件名：{} 文件大小：{} bytes‘.format(filename, info.file_size))

zipfile_getinfo.py

运行效果

[[email protected] mnt]# python3 zipfile_getinfo.py 文件名：test.py 文件大小：426 bytes文件：README.txt,不存在zip里面

5、查看zip里面文件的内容

#!/usr/bin/env python3# encoding: utf-8import zipfilewith zipfile.ZipFile(‘test.zip‘) as zf:    filenames = [‘test.py‘, ‘README.txt‘]    for filename in filenames:        try:            data = zf.read(filename)        except KeyError:            print(‘文件：{},不存在zip里面‘.format(filename))        else:            print(‘文件名：{} 文件内容：{}‘.format(filename, data))

zipfile_read.py

运行效果

[[email protected] mnt]# python3 zipfile_read.py 文件名：test.py 文件内容：b"#!/usr/bin/env python3\r\n"文件：README.txt,不存在zip里面

6、增加文件zip压缩

#!/usr/bin/env python3# encoding: utf-8import zipfilewith zipfile.ZipFile(‘write.zip‘,‘w‘) as zf:    print(‘增加test.py压缩‘)    zf.write(‘test.py‘)

zipfile_write.py

运行效果

[[email protected] mnt]# python3 zipfile_write.py 增加test.py压缩[[email protected] mnt]# ll-rw-r--r-- 1 root root  278 Jan 10 11:37 write.zip-rw-r--r-- 1 root root  160 Jan 10 11:37 zipfile_write.py

7、设置压缩模式压缩文件

#!/usr/bin/env python3# encoding: utf-8import zipfiletry:    import zlib    compression = zipfile.ZIP_DEFLATEDexcept (ImportError, AttributeError):    compression = zipfile.ZIP_STOREDmodes = {  # set集合    zipfile.ZIP_DEFLATED: ‘deflated‘,    zipfile.ZIP_STORED: ‘stored‘,}print(‘创建压缩文件‘)with zipfile.ZipFile(‘write_compression.zip‘, ‘w‘) as wf:    mode_name = modes[compression]    print(‘增加 test.py 文件压缩并且设置压缩模式‘, mode_name)    wf.write(‘test.py‘, compress_type=compression)

zipfile_write_compression.py

运行效果

[[email protected] mnt]# python3  zipfile_write_compression.py 创建压缩文件增加 test.py 文件压缩并且设置压缩模式 deflated[[email protected] mnt]# ll-rw-r--r-- 1 root root  256 Jan 10 14:11 write_compression.zip-rw-r--r-- 1 root root  542 Jan 10 14:11 zipfile_write_compression.py

8、压缩文件，并且修改被压缩的文件名

#!/usr/bin/env python3# encoding: utf-8import zipfilewith zipfile.ZipFile(‘write_artcname.zip‘, ‘w‘) as wf:    wf.write(‘test.py‘,arcname=‘artcle_name_test.py‘)

zipfile_write_arcname.py

运行效果

[[email protected] mnt]# python3 zipfile_write_arcname.py [[email protected] mnt]# ll-rw-r--r-- 1 root root  302 Jan 10 14:17 write_artcname.zip-rw-r--r-- 1 root root  167 Jan 10 14:16 zipfile_write_arcname.py[[email protected] mnt]# unzip -l write_artcname.zip Archive:  write_artcname.zip  Length      Date    Time    Name---------  ---------- -----   ----      166  01-10-2020 11:35   artcle_name_test.py---------                     -------      166                     1 file

9、从内存中获取数据，压缩为zip文件

#!/usr/bin/env python3# encoding: utf-8import zipfilemsg = ‘This Data did not exist in a file‘with zipfile.ZipFile(‘writestr.zip‘, ‘w‘, compression=zipfile.ZIP_DEFLATED) as zf:    zf.writestr(‘from_string.txt‘, msg)with zipfile.ZipFile(‘writestr.zip‘, ‘r‘) as zf:    print(zf.read(‘from_string.txt‘))

zipfile_writestr.py

运行效果

[[email protected] mnt]# python3 zipfile_writestr.py b‘This Data did not exist in a file‘[[email protected] mnt]# ll-rw-r--r-- 1 root root  163 Jan 10 14:25 writestr.zip-rw-r--r-- 1 root root  312 Jan 10 14:25 zipfile_writestr.py

10、压缩数据，并且设置被压缩文件的时间等参数

#!/usr/bin/env python3# encoding: utf-8import zipfileimport timemsg = ‘This Data did not exist in a file‘with zipfile.ZipFile(‘writestr_zipinfo.zip‘, ‘w‘) as zf:    info = zipfile.ZipInfo(‘from_string.txt‘, date_time=time.localtime(time.time()))    info.compress_type = zipfile.ZIP_DEFLATED    info.comment = ‘这是压缩的注释‘.encode(‘utf-8‘)    info.create_system = 0    zf.writestr(info, msg)

zipfile_writestr_zipinfo.py

运行效果

[[email protected] mnt]# python3 zipfile_writestr_info.py [[email protected] mnt]# unzip -l writestr_zipinfo.zip Archive:  writestr_zipinfo.zip  Length      Date    Time    Name---------  ---------- -----   ----       33  01-10-2020 14:36   from_string.txt这是压缩的注释---------                     -------       33                     1 file

11、往压缩文件，增加文件继续压缩的示例

#!/usr/bin/env python3# encoding: utf-8import zipfileprint(‘创建压缩zip‘)with zipfile.ZipFile(‘append.zip‘, ‘w‘) as zf:    zf.write(‘test.py‘)print(‘往append.zip文件增加新的文件‘)with zipfile.ZipFile(‘append.zip‘, ‘a‘) as af:    af.write(‘test.py‘, arcname=‘new_test.py‘)print(‘增加压缩文件完成‘)

zipfile_append.py

运行效果

[[email protected] mnt]# python3 zipfile_append.py 创建压缩zip往append.zip文件增加新的文件增加压缩文件完成[[email protected] mnt]# unzip -l append.zip Archive:  append.zip  Length      Date    Time    Name---------  ---------- -----   ----      166  01-10-2020 11:35   test.py      166  01-10-2020 11:35   new_test.py---------                     -------      332                     2 files

12、查看压缩文件里面所有的目录和文件名

#!/usr/bin/env python3# encoding: utf-8import zipfilewith zipfile.ZipFile(‘example.zip‘, ‘r‘) as rf:    print(rf.printdir())

zipfile_printdir.py

运行效果

[[email protected] mnt]# python3 zipfile_printdir.py File Name                                             Modified             Sizeadd/                                           2020-01-10 14:45:36            0add/test.zip                                   2020-01-10 09:58:18         1362add/write_artcname.zip                         2020-01-10 14:17:44          302add/writestr.zip                               2020-01-10 14:25:22          163content_update.txt                             2020-01-09 11:53:32          336

13、利用zipfile模块，把py代码转为pyc并且压缩打包成zip文件

#!/usr/bin/env python3# encoding: utf-8import zipfileif __name__ == ‘__main__‘:    with zipfile.PyZipFile(‘pyzipfile.zip‘, ‘w‘) as wf:        wf.debug = 3        print(‘增加Python多个文件‘)        wf.writepy(‘.‘)    for name in wf.namelist():        print(name)

zipfile_pyzipfile.py

运行效果

[[email protected] mnt]# python3 zipfile_pyzipfile.py 增加Python多个文件Adding files from directory .Adding test.pycAdding zipfile_pyzipfile.pyctest.pyczipfile_pyzipfile.pyc[[email protected] mnt]# unzip -l pyzipfile.zip Archive:  pyzipfile.zip  Length      Date    Time    Name---------  ---------- -----   ----      233  01-10-2020 14:57   test.pyc      349  01-10-2020 14:57   zipfile_pyzipfile.pyc---------                     -------      582                     2 files
