Python函数在定义的时候,默认参数L的值就被计算出来了,即[],因为默认参数L也是一个变量,它指向对象[],每次调用该函数,如果改变了L的内容,则下次调用时,默认参数的内容就变了,不再是函数定义时的[]了。 要修改上面的例子,我们可以用None这个不变对象来实现: def add_end(L=None): if L is None: L = [...

If I turn this function into an identity: def_reduce_any_error(error:Error):returnerror thenerr.throw()shows all the errors instead of just the first. I'm not sure of the other implications of that, but if someone wants to explore this further, then understanding the intent of that help...
