包方法：
GzipFile
open
gzip_file = gzip.open('B5-H.pickle.gz')
>>> type(tar_file)
<class 'gzip.GzipFile'>
tar_file1 = gzip.GzipFile('testtar.tar')
>>> type(tar_file1)
<class 'gzip.GzipFile'>
compress
s_in = b"Lots of content here"
s_out = gzip.compress(s_in)
>>> s_out
b'\x1f\x8b\x08\x00\xeb\x01\x1bd\x02\xff\xf3\xc9/)V\xc8OSH\xce\xcf+I\xcd+Q\xc8H-J\x05\x00~u \x8e\x14\x00\x00\x00'
decompress
>>> s_out = gzip.decompress(s_out)
>>> s_out
b'Lots of content here'
