Hi Lokesh,
we can pass lookup while parsing your json file which will make sure that
name is repetitive or not .
import json
def duplicate_checking_hook(pairs):
''' lookup for duplicate names'''
result = dict()
for key, val in pairs:
if key in result:
raise KeyError('Duplicate Key specified: %s % key)
result[key] = val
return result
>>> json.loads('''{"test":"hi","test":"bye"}''',
object_pairs_hook=duplicate_checking_hook)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/json/__init__.py", line 339, in loads
return cls(encoding=encoding, **kw).decode(s)
File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
obj, end = self.scan_once(s, idx)
File "<stdin>", line 5, in duplicate_checking_hook
KeyError: u'Duplicate key specified: a'
While
>>> json.loads('''{"test":"hi","test1":"bye"}''',
object_pairs_hook=duplicate_checking_hook)
{u'test': u'hi', u'test1': u'bye'}
>>>
def dupe_checking_hook(pairs):
result = dict()
for key,val in pairs:
if key in result:
raise KeyError("Duplicate key specified: %s" % key)
result[key] = val
return result
