如何基于几乎相同的键值从单个字典创建多个字典？

source_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
keys = ['key1', 'key2', 'key3']
values1 = [source_dict[key] + '_1' for key in keys]
values2 = [source_dict[key] + '_2' for key in keys]

dict1 = {key: value for key, value in zip(keys, values1)}
dict2 = {key: value for key, value in zip(keys, values2)}

print(dict1)
print(dict2)

{'key1': 'value1_1', 'key2': 'value2_1', 'key3': 'value3_1'}
{'key1': 'value1_2', 'key2': 'value2_2', 'key3': 'value3_2'}
