If you are using Python 3 and are only interested in the first two values, this is a good opportunity to use Extended Iterable Unpacking. Here are some short demos: >>> n1, n2, *other = map (int, input ().split ()) 1 2 3 4 >>> n1 1 >>> n2 2 >>> other [3, 4] other is the "wildcard" name that catches the remaining values. Web相应的，Python提供了一种返回值的机制，即一个函数可以返回多个值。这在别的语言中是很少见的。这既提供了很大的灵活性，但也带来了一些麻烦。麻烦之一就是too many values to unpack。 原因跟上面一样，赋值语句左边的元素和函数返回值个数不匹配。
