Zlib tutorials

[snippsat]

Code is for Python 2 which is dead💀
If change code and run with Python 3.9.

import zlib

MESSAGE = b"life of brian"

compressed_message = zlib.compress(MESSAGE)
decompressed_message = zlib.decompress(compressed_message)

print("original:", repr(MESSAGE))
print("compressed message:", repr(compressed_message))
print("decompressed message:", repr(decompressed_message))

Output:
original: b'life of brian'
compressed message: b'x\x9c\xcb\xc9LKU\xc8OSH*\xcaL\xcc\x03\x00!\x08\x04\xc2'
decompressed message: b'life of brian'

So it need to be bytes in and it give bytes out.
You can easy change later if need string.

>>> decompressed_message
b'life of brian'
>>> decompressed_message.decode()
'life of brian'

# Other way around
>>> s = 'life of brian'
>>> s
'life of brian'
>>> s.encode()
b'life of brian'
