Kirubakaran Athmanathan pyb...@kirubakaran.com added the comment:
The note added Keys in key/value pairs of JSON are always of the type
str. When a dictionary is converted into JSON, all the keys of the
dictionary are coerced to strings. is true for unicode keys too.
'{foo: bar}'

[issue6566] json.dumps converts None to null (not null)
Merlijn van Deen valhall...@gmail.com added the comment:
JSON does not have the distinction between bytes and unicode; py2 strings are
coerced into unicode.
I think it would be better to speak about 'JSON string' or 'JSON string
element' if it's JSON and about 'unicode' (2.7) or 'str' (3.x) when speaking
about the data that has been decoded again.
json.loads(json.dumps(boo))
u'boo'
json.loads(json.dumps({a: b}))
{u'a': u'b'}
(the keys will always be unicode in 2.7)

Bob Ippolito b...@redivi.com added the comment: JP is correct, this is how JSON works. The behavior of coercing keys to strings is often desirable, although I agree it could be confusing if you aren't familiar with the JSON spec. -- components: +Documentation -Library (Lib) ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6566 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue6566] json.dumps converts None to null (not null)
New submission from Sridhar Ratnakumar sridh...@activestate.com:
In [2]: json.dumps({'a': 1, 'b': {'c': 3, None: 5}})
Out[2]: '{a: 1, b: {c: 3, null: 5}}'
In [3]: j = json.dumps({'a': 1, 'b': {'c': 3, None: 5}})
In [4]: json.loads(j)
Out[4]: {u'a': 1, u'b': {u'c': 3, u'null': 5}}
I was surprised to note that None was converted to null instead of
null. This happens only in dicts and not, for example, lists:
In [5]: json.dumps([None, 1, a])
Out[5]: '[null, 1, a]'

The simplest repro:
In [6]: json.dumps({None: 3})
Out[6]: '{null: 3}'
In [7]: json.loads(json.dumps({None: 3}))
Out[7]: {u'null': 3}

Jean-Paul Calderone exar...@divmod.com added the comment:
Notice what it does to other dict keys:
simplejson.dumps({1: 1})
'{1: 1}'
In other words, I don't think this is a bug. It's how JSON works. JSON
dict keys are strings *only*.

Sridhar Ratnakumar sridh...@activestate.com added the comment: JSON dict keys are strings *only*. I might be helpful to point this out (along with other caveats) in the standard library documentation for JSON. An explicit mention of ``loads(dumps(x)) != x for certain structures`` would be nice. I, sir, was genuinely surprised to discover this. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6566 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
