要完成任务:添加到集合,但不更改行为,不需要functools。相反,您只需要一个返回您的函数的简单函数。

试试这个:

schedule_registry = set()

def register_scheduler(func):
  print(f"adding {func.__name__}")
  schedule_registry.add(func)
  return func

@register_scheduler
def foo():
    print("running foo")

@register_scheduler
def bar():
    print("running bar")

print(f"now running foo..., and registry has {len(schedule_registry)} items")

foo()

你应该看到:

adding foo
adding bar
now running foo..., and registry has 2 items
running foo
