我有多个齐普档案,其结构相同——它们含有XML档案。 每一卷卷宗中的所有档案都是独一无二的(在齐普档案中没有重复)。 我需要将所有XML文件从所有齐p文档合并成单一齐p文件(其结构与原始齐p文档相同)。 就如何最好地做到这一点提出建议? 感谢。

This is the shortest version I could come up with:

>>> import zipfile as z
>>> z1 = z.ZipFile( z1.zip ,  a )
>>> z2 = z.ZipFile( z2.zip ,  r )
>>> z1.namelist()
[ a.xml ,  b.xml ]
>>> z2.namelist()
[ c.xml ,  d.xml ]
>>> [z1.writestr(t[0], t[1].read()) for t in ((n, z2.open(n)) for n in z2.namelist())]
[None, None]
>>> z1.namelist()
[ a.xml ,  b.xml ,  c.xml ,  d.xml ]
>>> z1.close()

如果不测试替代方法,对我来说,这是最佳解决办法(也许最明显的是!) ,因为假设双手档案都包含同样数量的数据,这种方法只需要压缩和压制一半的数据(1个档案)。

在此,我通过“@mac”来到这里。 请注意,目前如何执行第一份齐普案卷,以包含其他齐普案的所有档案。

import zipfile as z

zips = [ z1.zip ,  z2.zip ,  z3.zip ]

"""
Open the first zip file as append and then read all
subsequent zip files and append to the first one
"""
with z.ZipFile(zips[0],  a ) as z1:
    for fname in zips[1:]:
        zf = z.ZipFile(fname,  r )
        for n in zf.namelist():
            z1.writestr(n, zf.open(n).read())
