python - 将单个装饰器应用于多种功能

我已经搜索过了，但是我看到的结果却恰恰相反：对一个函数应用多个decorator。
我想简化这个模式。有没有一种方法可以将这个单一的decorator应用到多个函数如果没有，我如何重写上面的内容以减少重复？

from mock import patch

@patch('somelongmodulename.somelongmodulefunction')
def test_a(patched):
    pass  # test one behavior using the above function

@patch('somelongmodulename.somelongmodulefunction')
def test_b(patched):
    pass  # test another behavior

@patch('somelongmodulename.somelongmodulefunction')
def test_c(patched):
    pass  # test a third behavior

from mock import patch

patched_name = 'somelongmodulename.somelongmodulefunction'

@patch(patched_name)
def test_a(patched):
    pass  # test one behavior using the above function

@patch(patched_name)
def test_b(patched):
    pass  # test another behavior

@patch(patched_name)
def test_c(patched):
    pass  # test a third behavior

最佳答案

如果您只想让“long”函数调用一次，并用结果装饰所有三个函数，只需这样做。

my_patch = patch('somelongmodulename.somelongmodulefunction')

@my_patch
def test_a(patched):
    pass

@my_patch
def test_b(patched):
    pass
