为json返回集合中选定的键

data = {
    "key1": "value1",
    "key2": "value2",
    "key3": "value3"
}

selected_keys = ["key1", "key3"]

result = {key: data[key] for key in selected_keys if key in data}

print(result)

{'key1': 'value1', 'key3': 'value3'}

data = {
    "key1": "value1",
    "key2": "value2",
    "key3": "value3"
}

selected_keys = ["key1", "key3"]

result = dict(map(lambda key: (key, data[key]), filter(lambda key: key in data, selected_keys)))

print(result)

{'key1': 'value1', 'key3': 'value3'}
