The documentation of urllib.parse contains:
    URL encoded
    a “url-encoded” string
I am not sure what the official usage is, either in Python or more 
generally. Actually, in formal W3C documents the term used is percent-
encoding (with the hyphen, even when used as a noun). I don't expect 
anyone to use "percent-encoding" but maybe, especially as an adjective, 
the phrase in Python documentation should consistently be "url-encoded"?

What is referred to as URL-encoded or URL encoded is technically 'percent-encoding'. Consistency would desirable and I think 'URL encoded' is okay. It involves a minor change in removing '-' in some places. Once trunk opens, I shall make those changes in the docs referenced here.

Hello.

I’m not a native speaker, but I know that you need hyphens inside adjectives: URI-encoded, percent-encoded, built-in <0.2 wink>, etc.

I’m willing to produce a patch that changes “URL-encoded” to “percent-encoded”.

Regards
