import json

# 原始 JSON 数据
json_data = '''
[
    {"id": 1, "name": "MOVE"},
    {"id": 2, "name": "LEFT_DOWN"},
    {"id": 3, "name": "LEFT_UP"},
    {"id": 4, "name": "RIGHT_DOWN"},
    {"id": 5, "name": "RIGHT_UP"},
    {"id": 6, "name": "SCROLL_DOWN"},
    {"id": 7, "name": "SCROLL_UP"},
    {"id": 8, "name": "SCROLL_PUSH"},
    {"id": 9, "name": "SCROLL_PULL"}
]
'''

# 将JSON数据解析为Python对象
data = json.loads(json_data)

# 选择特定id和name的组合
result_dict = {entry['name']: entry['id'] for entry in data}

print(result_dict.get('MOVE'))
