将分层路径数组转换为JSON

def convert_to_json(path_array):
    result = {}  # 创建空的JSON对象作为结果容器
    
    for path in path_array:
        current = result  # 当前层级的JSON对象
        for level in path:
            if level not in current:
                current[level] = {}  # 创建新的JSON对象
            current = current[level]  # 进入下一层级
        
    return result

# 示例路径数组
path_array = [
    ['a', 'b', 'c'],
    ['a', 'b', 'd'],
    ['a', 'e'],
    ['f']
]

# 转换为JSON
json_data = convert_to_json(path_array)

# 打印结果
print(json_data)

{
  "a": {
    "b": {
      "c": {},
      "d": {}
    },
    "e": {}
  },
  "f": {}
