zipfile

The zipfile library provides ZIP archive reading and writing, similar to Python’s zipfile module.

Available Functions

Function	Description
`ZipFile(path, mode="r")`	Open a ZIP archive for reading or writing.
`is_zipfile(path)`	Check if a file is a valid ZIP archive.

ZipFile Methods

Method	Description
`namelist()`	Return a list of archive member names.
`read(name)`	Read a member as a string.
`extract(member, path=".")`	Extract a single member.
`extractall(path=".")`	Extract all members.
`write(filename, arcname=None)`	Add a file to the archive (write mode).
`writestr(name, data)`	Write a string as a member (write mode).
`close()`	Close the archive.

Usage

Reading

    
import zipfile

zf = zipfile.ZipFile("archive.zip")
for name in zf.namelist():
    print(name, len(zf.read(name)))
zf.close()

Extracting

    
import zipfile

with zipfile.ZipFile("archive.zip") as zf:  # close() is called automatically
    zf.extractall("/tmp/output")

Creating

    
import zipfile

zf = zipfile.ZipFile("output.zip", "w")
zf.writestr("readme.txt", "hello world")
zf.write("/etc/hostname", "config/hostname")
zf.close()

Checking

    
import zipfile

if zipfile.is_zipfile("maybe.zip"):
    print("valid zip")

Security Considerations

This is an extended library, requiring registration in Go. Both the archive path and extraction destination must be within allowedPaths. Zip-slip (path traversal via crafted entry names) is blocked automatically. See Library Registration and the Security Guide.
