how to filter json array in python

The following snippet of code does exactly what you want, but BEWARE that your input (as written in the question) is not a valid json string, you can check here: http://jsonlint.com.

import json

input_json = 
[
    {
        type: 1,
        name: name 1
    },
    {
        type: 2,
        name: name 2
    },
    {
        type: 1,
        name: name 3
    }
]

# Transform json input to python objects
input_dict = json.loads(input_json)

# Filter python objects with list comprehensions
output_dict = [x for x in input_dict if x[type] == 1]

# Transform python object back into json
output_json = json.dumps(output_dict)

# Show json
print output_json

Simply

print [obj for obj in dict if(obj[type] == 1)]

...         type: 1,
...         name: name 3
...     }
... ]
>>> filter(lambda x: x[type] == 1, obj)
<filter object at 0x7fd98805ca00>
>>> list(filter(lambda x: x[type] == 1, obj))
[{type: 1, name: name 1}, {type: 1, name: name 3}]
