Maybe it isn't worse, but the real alternative is:

import zlib import base64 base64.b64encode(zlib.compress(s)) Encodings cover up eclectic interfaces, where those interfaces fit a basic pattern -- data in, data out. So should I write 3.1415.encode("sin") or would that be 3.1415.decode("sin")

The ambiguity shows that "sin" is clearly not an encoding. Doesn't read right anyway.

[0.3, 0.35, ...].encode('fourier') would be sensible though. Except of course lists don't have an encode method; but that's just a convenience of strings and unicode because those objects are always data, where lists are only sometimes data. If extended indefinitely, the namespace issue is notable. But it's not going to be extended indefinitely, so that's just a theoretical problem.

What about

"http://www.python.org".decode("URL")

you mean 'a%20b'.decode('url') == 'a b'? That's not what you meant, but nevertheless that would be an excellent encoding ;)
