1、判断是否是zip文件

#!/usr/bin/env python3#encoding: utf-8

importzipfile

filenames= [‘tcp_server.py‘, ‘test.py‘, ‘test.zip‘]for filename infilenames:print(‘{:>15} {}‘.format(filename, zipfile.is_zipfile(filename)))

zipfile_is_zipfile.py

运行效果

[root@ 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-8

importzipfile

with zipfile.ZipFile(‘test.zip‘, ‘r‘) as zf:print(zf.namelist())

zipfile_namelist.py

运行效果

[root@ 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-8

importzipfileimportdatetimedefprint_info(archive_name):

with zipfile.ZipFile(archive_name) as zf:for info inzf.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

[root@ mnt]# python3 zipfile_infolist.py

tcp_client.py

4、指定文件名查看zip里面的文件信息

#!/usr/bin/env python3#encoding: utf-8

importzipfile

with zipfile.ZipFile(‘test.zip‘) as zf:

filenames= [‘test.py‘, ‘README.txt‘]for filename infilenames:try:

info=zf.getinfo(filename)exceptKeyError: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

[root@ mnt]#python3 zipfile_getinfo.py

文件名：test.py 文件大小：426bytes

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-8

importzipfile

with zipfile.ZipFile(‘test.zip‘) as zf:

filenames= [‘test.py‘, ‘README.txt‘]for filename infilenames:try:

data=zf.read(filename)exceptKeyError: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

[root@ 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-8

importzipfile

with 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

[root@ mnt]# python3 zipfile_write.py

增加test.py压缩

[root@ 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-8

importzipfiletry:importzlib

compression=zipfile.ZIP_DEFLATEDexcept(ImportError, AttributeError):

compression=zipfile.ZIP_STORED

modes= { #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

[root@ 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

[root@ 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-8

importzipfile

with 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

[root@ mnt]#python3 zipfile_write_arcname.py

[root@ mnt]#ll

-rw-r--r-- 1 root root 302 Jan 10 14:17write_artcname.zip-rw-r--r-- 1 root root 167 Jan 10 14:16zipfile_write_arcname.py

[root@ mnt]#unzip -l write_artcname.zip

Archive: write_artcname.zip

Length Date Time Name--------- ---------- ----- ----

166 01-10-2020 11:35artcle_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-8

importzipfile

msg= ‘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

[root@ mnt]#python3 zipfile_writestr.py

b‘This Data did not exist in a file‘[root@ mnt]#ll

-rw-r--r-- 1 root root 163 Jan 10 14:25writestr.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-8

importzipfileimporttime

msg= ‘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

[root@ mnt]#python3 zipfile_writestr_info.py

[root@ mnt]#unzip -l writestr_zipinfo.zip

Archive: writestr_zipinfo.zip

Length Date Time Name--------- ---------- ----- ----

33 01-10-2020 14:36from_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-8

importzipfileprint(‘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:
