Python can't parse JSON with extra trailing comma

Question

This code:

import json
s = \'{ \"key1\": \"value1\", \"key2\": \"value2\", }\'
json.loads(s)

produces this error in Python 2:

Answer 1

That's because an extra , is invalid according to JSON standard.

An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma).

If you really need this, you could wrap python's json parser with jsoncomment. But I would try to fix JSON in the origin.
