python: unicode data is not equal to unicode data

Question

i has some json works like this.

>>> j = '{"a":5}'
>>> js = json.loads(j)
>>> for key in js:
...     key
...     type(key)
...     key is unicode('a')
... 
u'a'
<type 'unicode'>
False

In my opinion last value of output should be true. Plese helpme to find my mistake.

Answer 1

Why are you using is here? You just want to compare:

key == unicode('a')

or even better:

key == u'a'
