如何在字典中将键转换为值，并将值转换为键

def swap_dict(dictionary):
    new_dict = {}
    for key, value in dictionary.items():
        new_dict[value] = key
    return new_dict

# 示例字典
my_dict = {'apple': 'fruit', 'carrot': 'vegetable', 'orange': 'fruit'}

# 将键转换为值，并将值转换为键
new_dict = swap_dict(my_dict)

print(new_dict)

{'fruit': 'orange', 'vegetable': 'carrot'}
