DeflateError
✓ from deflate import DeflateError

Demonstrates basic compression and decompression using the Deflate class.

from deflate import Deflate data = b'Hello, world! ' * 1000 compressed = Deflate.compress(data, format='deflate') decompressed = Deflate.decompress(compressed, format='deflate') assert data == decompressed print('Success!')
Debug
Known issues
breakingIn version 0.7.0, DeflateError was removed; invalid gzip data now raises ValueError instead of DeflateError. If your code catches DeflateError, it will break.
fix
Replace `except DeflateError` with `except ValueError`.
affects: >=0.7.0
gotchaCompression level 0 means no compression, not default. Level 6 is the default. If you pass level=0 expecting 'fastest', you get uncompressed data.
fix
Use level=6 for default compression, or any level 1-12 for libdeflate (12 is maximum).
affects: all
deprecatedThe function `deflate.deflate` and `deflate.inflate` are deprecated since 0.7.0. Use the Deflate class instead.
fix
Replace `deflate.deflate(data)` with `Deflate.compress(data, format='deflate')`.
affects: >=0.7.0
