z = ZipFile(file, mode="r", compression=ZIP_STORED, allowZip64=True,
compresslevel=None)
file: Either the path to the file, or a file-like object.
If it is a path, the file will be opened and closed by ZipFile.
mode: The mode can be either read 'r', write 'w', exclusive create 'x',
or append 'a'.
compression: ZIP_STORED (no compression), ZIP_DEFLATED (requires zlib),
ZIP_BZIP2 (requires bz2) or ZIP_LZMA (requires lzma).
allowZip64: if True ZipFile will create files with ZIP64 extensions when
needed, otherwise it will raise an exception when this would
be necessary.
compresslevel: None (default for the given compression type) or an integer
specifying the level to pass to the compressor.
When using ZIP_STORED or ZIP_LZMA this keyword has no effect.
When using ZIP_DEFLATED integers 0 through 9 are accepted.
When using ZIP_BZIP2 integers 1 through 9 are accepted.

name is a string for the file name within the ZIP file, or a ZipInfo
object.
mode should be 'r' to read a file already in the ZIP file, or 'w' to
write to a file newly added to the archive.
pwd is the password to decrypt files (only used for reading).
When writing, if the file size is not known in advance but may exceed
2 GiB, pass force_zip64 to use the ZIP64 format, which can handle large
files. If the size is known in advance, it is best to pass a ZipInfo
instance for name, with zinfo.file_size set.

If pathname is a package directory, search the directory and
all package subdirectories recursively for all *.py and enter
the modules into the archive. If pathname is a plain
directory, listdir *.py and enter all modules. Else, pathname
must be a Python *.py file and the module will be put into the
archive. Added modules are always module.pyc.
This method will compile the module.py into module.pyc if
necessary.
If filterfunc(pathname) is given, it is called with every argument.
When it is False, the file or directory is skipped.

A pathlib-compatible interface for zip files.
Consider a zip file with this structure::
.
├── a.txt
└── b
├── c.txt
└── d
└── e.txt
>>> data = io.BytesIO()
>>> zf = ZipFile(data, 'w')
>>> zf.writestr('a.txt', 'content of a')
>>> zf.writestr('b/c.txt', 'content of c')
>>> zf.writestr('b/d/e.txt', 'content of e')
>>> zf.filename = 'abcde.zip'
Path accepts the zipfile object itself or a filename
>>> root = Path(zf)
From there, several path operations are available.
Directory iteration (including the zip file itself):
>>> a, b = root.iterdir()
>>> a
Path('abcde.zip', 'a.txt')
>>> b
Path('abcde.zip', 'b/')
name property:
>>> b.name
'b'
join with divide operator:
>>> c = b / 'c.txt'
>>> c
Path('abcde.zip', 'b/c.txt')
>>> c.name
'c.txt'
Read text:
>>> c.read_text()
'content of c'
existence:
>>> c.exists()
True
>>> (b / 'missing.txt').exists()
False
Coercion to string:
>>> str(c)
'abcde.zip/b/c.txt'
