It looks like you are trying to produce JSON; if so, use the json
module:
>>> import json
>>> print json.dumps({'AAA': 1, 'BBB': 2, 'CCC': 3})
{"AAA": 1, "BBB": 2, "CCC": 3}
The pprint()
function produces Python representations, not JSON and quoting styles are not configurable. Don’t confuse the two syntaxes. JSON may at first glance look a lot like Python but there are more differences than just quoting styles:
- JSON is limited to a few specific types only (
{...}
objects with key-value pairs, [...]
arrays, "..."
strings, numbers, booleans and nulls). Python data structures are far richer.
- Python dictionary keys can be any hashable object, JSON object keys can only ever be strings.
- JSON booleans are written in lowercase,
true
and false
. Python uses title-case, True
and False
.
- JSON uses
null
to signal the absence of a value, Python uses None
.
- JSON strings use UTF-16 codepoints, any non-BMP codepoint is encoded using surrogate pairs. Apart from a handful of single-letter backslash escapes such as
and "
arbitrary codepoint escapes use uXXXX
16-bit hexadecimal notation. Python 3 strings cover all of Unicode, and the syntax supports xXX
, uXXXX
, and UXXXXXXXX
8, 16 and 32-bit escape sequences.
If you want to produce indented JSON output (a bit like pprint()
outputs indented Python syntax for lists and dictionaries), then add indent=4
and sort_keys=True
to the json.dumps()
call:
>>> print json.dumps({'AAA': 1, 'CCC': 2, 'BBB': 3}, indent=4, sort_keys=True)
{
"AAA": 1,
"BBB": 2,
"CCC": 3
}
