如何在python中将带有列表的字典转换为每个关联键值的个数不等的字典列表？

data = {'key1': [1, 2, 3], 'key2': [4, 5], 'key3': [6, 7, 8, 9]}

result = [{k: v[i] for k, v in data.items()} for i in range(max(len(v) for v in data.values()))]

print(result)

data = {'key1': [1, 2, 3], 'key2': [4, 5], 'key3': [6, 7, 8, 9]}

result = [{k: v[i] for k, v in data.items()} for i in range(max(len(v) for v in data.values()))]

print(result)

[{'key1': 1, 'key2': 4, 'key3': 6}, {'key1': 2, 'key2': 5, 'key3': 7}, {'key1': 3, 'key2': None, 'key3': 8}, {'key1': None, 'key2': None, 'key3': 9}]
