zipfile.ZipFile

ZIP archives

A class for reading, creating and appending to ZIP archives; it accepts a path or a file object.

Syntax

zipfile.ZipFile(file, mode='r', compression=ZIP_STORED, allowZip64=True, compresslevel=None)

The default is compression=ZIP_STORED: files go in with no compression at all, so the 'archive' is as big as the sources — use ZIP_DEFLATED to compress. Mode 'w' silently overwrites an existing archive, 'a' appends, and writing a name that already exists adds a second entry (with a UserWarning) instead of replacing it. read() returns bytes; decoding text is up to you.

Examples

import os, zipfile
with open('a.txt', 'w', encoding='utf-8') as f:
    f.write('hello ' * 100)
with zipfile.ZipFile('stored.zip', 'w') as z:
    z.write('a.txt')
with zipfile.ZipFile('packed.zip', 'w', compression=zipfile.ZIP_DEFLATED) as z:
    z.write('a.txt')
print(os.path.getsize('stored.zip') > os.path.getsize('packed.zip'))  # → True — по умолчанию сжатия нет

import zipfile
with zipfile.ZipFile('notes.zip', 'w', compression=zipfile.ZIP_DEFLATED) as z:
    z.writestr('docs/readme.txt', 'привет')
with zipfile.ZipFile('notes.zip') as z:
    print(z.namelist())  # → ['docs/readme.txt']
    data = z.read('docs/readme.txt')
    print(type(data).__name__)  # → bytes
    print(data.decode('utf-8'))  # → привет
