Hi,大家好,我是编程小6,很荣幸遇见你,我把这些年在开发过程中遇到的问题或想法写出来,今天说一说
python zipfile extractall_python读取压缩包中的所有文件,希望能够帮助你!!!。
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
Comment : b''Modified :2020-01-09 18:01:58System : Windows
Zip Version :63Compressed :221bytes
UnCompressed :301bytes
tcp_server.py
Comment : b''Modified :2020-01-09 18:15:06System : Windows
Zip Version :63Compressed :511bytes
UnCompressed :996bytes
test.py
Comment : b''Modified :2020-01-09 16:58:52System : Windows
Zip Version :63Compressed :206bytes
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-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:
af.write('test.py', arcname='new_test.py')print('增加压缩文件完成')
zipfile_append.py
运行效果
[root@ 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
[root@ mnt]#unzip -l append.zip
Archive: append.zip
Length Date Time Name--------- ---------- ----- ----
166 01-10-2020 11:35test.py166 01-10-2020 11:35new_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-8
importzipfile
with zipfile.ZipFile('example.zip', 'r') as rf:print(rf.printdir())
zipfile_printdir.py
运行效果
[root@ mnt]#python3 zipfile_printdir.py
File Name Modified Size
add/ 2020-01-10 14:45:360
add/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.txt2020-01-09 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-8
importzipfileif __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 inwf.namelist():print(name)
zipfile_pyzipfile.py
运行效果
[root@ mnt]#python3 zipfile_pyzipfile.py
增加Python多个文件
Adding filesfromdirectory .
Adding test.pyc
Adding zipfile_pyzipfile.pyc
test.pyc
zipfile_pyzipfile.pyc
[root@ mnt]#unzip -l pyzipfile.zip
Archive: pyzipfile.zip
Length Date Time Name--------- ---------- ----- ----
233 01-10-2020 14:57test.pyc349 01-10-2020 14:57zipfile_pyzipfile.pyc--------- -------
582 2 files
