如何在字典中将set改为list，并按字母顺序的键排序？

my_dict = {'a': {1, 2, 3}, 'b': {4, 5, 6}, 'c': {7, 8, 9}}
my_dict = {k: list(v) for k, v in my_dict.items()}

sorted_keys = sorted(my_dict.keys())

from collections import OrderedDict

sorted_dict = OrderedDict()
for key in sorted_keys:
    sorted_dict[key] = my_dict[key]

from collections import OrderedDict

my_dict = {'a': {1, 2, 3}, 'b': {4, 5, 6}, 'c': {7, 8, 9}}

# 将set改为list
my_dict = {k: list(v) for k, v in my_dict.items()}

# 按字母顺序的键排序
sorted_keys = sorted(my_dict.keys())

# 创建新的有序字典
sorted_dict = OrderedDict()
for key in sorted_keys:
    sorted_dict[key] = my_dict[key]

print(sorted_dict)
