API Reference

Function	Description
compress.deflate(input) -> str	Compress string (returns hex-encoded data)
compress.inflate(data) -> str	Decompress hex data back to string
compress.ratio(orig, comp) -> int	Compression ratio as percentage
compress.gzip_file(in, out) -> int	gzip compress a file

Examples

String Compression

import compress

let data = "Hello World! " * 100
let compressed = compress.deflate(data)
let restored = compress.inflate(compressed)
assert restored == data

let ratio = compress.ratio(data, compressed)
print(f"Compressed to {str(ratio)}% of original")

File Compression

import compress

compress.gzip_file("data.txt", "data.txt.gz")
compress.gunzip_file("data.txt.gz", "data_restored.txt")

Note: Short strings may not compress well (zlib header overhead). Compression is most effective on larger, repetitive data.
