在Python3中自动创建字典分支

def create_dict_branch(keys, value):
    result = {}
    current_dict = result
    for key in keys[:-1]:
        if key not in current_dict:
            current_dict[key] = {}
        current_dict = current_dict[key]
    current_dict[keys[-1]] = value
    return result

# 示例用法
keys = ['branch1', 'branch2', 'branch3']
value = 'leaf_value'
result = create_dict_branch(keys, value)
print(result)

{
    'branch1': {
        'branch2': {
            'branch3': 'leaf_value'
        }
    }
}
