ZipFile. ZipFile (file[, mode[, compression[, AllowZip64]])

*zipfile (Path package name, mode, compressed or packaged, optional allowZip64)

function: Create a ZipFile object that represents a zip file.

-parameter file represents the path or class file object (File-like object)
- The parameter mode indicates the pattern of opening the zip file, the default value is R

Span style= "font-family: italics; Font-size:18px "> W means creating a new zip document or overwriting an existing zip document
a Represents appending data to an existing ZIP document.
-parameter compression represents the compression method used when writing a zip document
ZipFile. Zip_stored is just a storage mode and does not compress the file, this is the default value
ZipFile. zip_deflated compressing the file
-if the zip file size to be manipulated exceeds 2G, The ALLOWZIP64 should be set to true.
