Examples

JSONPath

import jsonpath

data = {
    "users": [
        {"name": "Sue", "score": 100},
        {"name": "John", "score": 86},
        {"name": "Sally", "score": 84},
        {"name": "Jane", "score": 55},
    ]
}

user_names = jsonpath.findall("$.users[?@.score < 100].name", data)
print(user_names) # ['John', 'Sally', 'Jane']

JSON Pointer

Since version 0.8.0, we include an RFC 6901 compliant implementation of JSON Pointer. See JSON Pointer quick start, guide and API reference

from jsonpath import pointer

data = {
    "users": [
        {"name": "Sue", "score": 100},
        {"name": "John", "score": 86},
        {"name": "Sally", "score": 84},
        {"name": "Jane", "score": 55},
    ]
}

sue_score = pointer.resolve("/users/0/score", data)
print(sue_score)  # 100

jane_score = pointer.resolve(["users", 3, "score"], data)
print(jane_score)  # 55

JSON Patch

Since version 0.8.0, we also include an RFC 6902 compliant implementation of JSON Patch. See JSON Patch quick start and API reference

from jsonpath import patch

patch_operations = [
    {"op": "add", "path": "/some/foo", "value": {"foo": {}}},
    {"op": "add", "path": "/some/foo", "value": {"bar": []}},
    {"op": "copy", "from": "/some/other", "path": "/some/foo/else"},
    {"op": "add", "path": "/some/foo/bar/-", "value": 1},
]

data = {"some": {"other": "thing"}}
patch.apply(patch_operations, data)
print(data) # {'some': {'other': 'thing', 'foo': {'bar': [1], 'else': 'thing'}}}
