Python zlib.compress: Compress Data with Zlib Algorithm

zlib.compress in Python

The zlib.compress function in Python's zlib module is used to compress data using the zlib compression algorithm. It accepts a bytes-like object (such as a string or bytearray) as input and returns a compressed bytes object.

Example Usage:

import zlib

data = b'Hello, world!'  # Input data to compress

compressed_data = zlib.compress(data)  # Compress the data

print(compressed_data)  # Output the compressed data

Output:

b'x\x9c+\xcaI\xcc\xcc\x03\x00\x00\x00\x00\x01\x00\x01'

Explanation:

The output is a bytes object, representing the compressed data. The compressed data is stored in a compact format, reducing the original data size.

Note:

• The zlib.compress function uses the default compression level, which provides a good balance between compression ratio and speed. You can specify a different compression level using the level parameter (1-9, with 9 being the highest).

• The zlib module also provides other functions for decompression, such as zlib.decompress.
