Python压缩&解压缩

 

Python中常用的压缩模块有zipfile、tarfile、gzip

 

1.zipfile模块的简单使用

import zipfile

# 压缩
z1 = zipfile.ZipFile(\'zip_test\', \'w\')
z1.write(\'src\')
z1.write(\'dst4\')
z1.close()

# 解压缩
with zipfile.ZipFile(\'zip_test\', \'r\') as z2:
    print(z2.read(\'src\').decode())  # 查看压缩包中src文件内容
    z2.extractall(\'zip123\')         # 解压文件到zip123目录下

 

2.tarfile模块的简单使用

import tarfile

# 压缩
t1 = tarfile.TarFile(\'tar_test\', \'w\')
t1.add(\'src\', \'dst2\')
t1.close()

# 解压缩
with tarfile.TarFile(\'tar_test\') as t2:
    t2.extractall(\'tar123\')     # 解压文件到tar123目录下

 

3.gzip模块的简单使用

import gzip

f = open(\'src\', encoding=\'utf-8\').read()
f = f.encode(encoding=\'utf-8\')
print(type(f))

with gzip.GzipFile(\'gzip_test\', \'w\') as g1:
    g1.write(f)

with gzip.GzipFile(\'gzip_test\') as g2:
    print(g2.read().decode())
    print(type(g2))
