ZipFile 压缩单个文件
python
import zipfile
import os
with zipfile.ZipFile('log.zip', 'w') as z:
z.write('log.log')
解压文件
python
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
python
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
python
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
python
def viewfile(zipfilename):
with zipfile.ZipFile(zipfilename, 'r') as z:
print(z.namelist())
viewfile('a.zip')
**TarFile** 压缩文件
python
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
python
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
python
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
python
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')
