c = result[0] 的意思是result中的第一个值。前面调用函数得出长方形的周长和面积，把64，256存到result中，现在把这个第一个值，也就是64存到变量c里，再打印出来。如果还不懂就回去看看前面关于列表索引那一块吧

这个是根据需要来设置的，第一段代码if 与 print之间与print之后的num+=1均是因为要将num的量增加1以便于后续运算；只是如果num<10，continue后面的代码无法运行，但是为了整体依然需要num+=1，故在continue之前再次放了num+=1，其实不是放在print前后的问题，而是放在continue前后的问题。要理解continue跳出循环的用法。第二个最后print输出的是while-if嵌套语句循环执行后的sum，所以放在最后，而num+=1的放法也是根据contin...

def average(*args): b = 0 if len(args) == 0: return b else: for i in args: b += i avg = b / len(args) return avg a=[1, 2, 3, 4, 5] print(average(*a)) <-----需要在前面加* 才會接受tuple/list用法
