[issue36088] zipfile cannot handle zip in zip

[Liyu Gong]

New submission from Liyu Gong <gongliyu at gmail.com>:

Suppose a.zip is z zip file containing 'abc/def/1.txt'

zf = zipfile.ZipFile('a.zip')
memf = zf.open('abc/def/1.txt', 'r')
zf2 = zipfile.ZipFile(memf) 

will raise an error. However, when a.zip is a tar file containing 'abc/def/1.txt', the following codes

tf = tarfile.open('a.zip')
memf = tf.open('abc/def/1.txt', 'r')
zf2 = zipfile.ZipFile(memf) 

works well. Is it a known issue?

Thanks!
