在列表理解中调用方法的mock.patch字典失败

from unittest.mock import patch

def my_function():
    my_dict = {'key': 'value'}
    return [my_dict['key'] for _ in range(3)]

with patch.dict(my_dict, {'key': 'mocked_value'}):
    result = my_function()
    print(result)  # 输出: ['mocked_value', 'mocked_value', 'mocked_value']

    with patch.dict(my_dict, {'key': 'mocked_value'}):
        return [my_dict['key'] for _ in range(3)]

result = my_function()
print(result)  # 输出: ['mocked_value', 'mocked_value', 'mocked_value']
