我正在尝试使用2个装饰器时获得正确的函数名称。

2 - ;自定义时序装饰器
from memory_profiler import profile按以下定义使用它们
def timing(f):
@wraps(f)
def wrapper(*args, **kwargs):
start = time()
result = f(*args, **kwargs)
end = time()
print 'Elapsed time: {} - {}'.format(wrapper.__name__, end - start)
return result
return wrapper
问题是这两个函数单独运行良好但是当一起使用时，我没有通过时序装饰器获得正确的名称。我总是得到@timing
@profile
def my_function():
something.....
而不是实际的函数名。
如何获取实际的函数名而不是将“wrapper”作为函数名？
