dump produces malformed yaml?

[lolmaus]

yaml.dump({
  attributes: {
    image-url: "http://www.2do2go.ru/uploads/full/a99dca2d765bb9c034ea8fbf315a48b2_w960_h2048.jpg",
    position: 6
  }
})

Expected output:

---
attributes:
  image-url: "http://www.2do2go.ru/uploads/full/a99dca2d765bb9c034ea8fbf315a48b2_w960_h2048.jpg"
  position: 6

Actual output:

attributes: {image-url: 'http://www.2do2go.ru/uploads/full/a99dca2d765bb9c034ea8fbf315a48b2_w960_h2048.jpg',
  position: 6}

When I try to run actual output in http://codebeautify.org/yaml-validator , it reports:

Error : Malformed inline YAML string "{image-url: 'http://www.2do2go.ru/uploads/full/a99dca2d765bb9c034ea8fbf315a48b2_w960_h2048.jpg'," at line 1 (near "attributes: {image-url: 'http://www.2do2go.ru/uploads/full/a99dca2d765bb9c034ea8fbf315a48b2_w960_h2048.jpg',")

Hrm, the result is definitely formatted incorrectly, I'll look into that asap.

It's not malformed, though. The site you linked can't parse some examples from the yaml spec.

So, this is the format that PyYAML dumps to by default. I'm closing this ticket in favour of #25 which covers other cases of dodgy default formatting.
