[ Python ]请教一个闭包传参的问题

各位大佬，下面的代码，嵌套函数定义def w():时，如果不传参，输入就符合预期，如果传了上层参数def w(*l):，结果就会报错。 请问传参不传参，影响在哪里呢？

def f(*l):
    yield from l

def closure(*l):
    a=f(*l)
    def w(): # 这里是 def w(*l)下面就会报错，报错内容最下方
        nonlocal a
        try:
            return next(a)
        except Exception:
            a=f(*l)
            return next(a)
    return w

c=closure(1,2)
for i in range(5):
    print(c())

输出为:

1
2
1
2
1

报错为:

1
2
