Oh indeed.

The former, I guess.

I guess the hash is SHA1, right?

Maybe we could make something like:

  (define-syntax-rule (pypi-origin package sha1 sha256-string)
    (origin
      (method url-fetch)
      (uri (string-append … sha1 …))
      (sha256 (base32 sha256-string))))

and then use it like:

  (package
    (name "python-foo")
    (source (pypi-origin "foo" "cabba9e" "somelongstring")))

?
