'''亲密数 (如果a的所有正因子和等于b,b的所有正因子和等于a,因子包括1但不包括本身,且a不等于b,则称a,b为亲密数对.一般通过叠代编程求出相应的亲密数对)'''n = 3000def fun01(n): s = 0 for i in range(1,n): if n % i == 0: s += i return sfor i in range(1,n): a = fun01(i) if i == fun01(a) and i < a: print(i,a)…
The Zen of Python, by Tim Peters Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. Readability counts. Special…
在某些编程语言中,例如 C/C++.C#.PHP.Java.JavaScript 等等,do-while 是一种基本的循环结构. 它的核心语义是:先执行一遍循环体代码,然后执行一遍条件语句,若条件语句判断为真,则继续执行循环体代码,并再次执行条件语句:直到条件语句判断为假,则跳出循环结构. 流程图如下(Java 示例): // 打印小于 20 的数字 public class Test { public static void main(String[] args){ int x = 10; d…
笨办法学python第36节,我写的代码如下: from sys import exit def rule(): print "Congratulations! You made the right choice." print "But is also a terrible choice." print "You have to abide by the contract of the devil." print "Input you…
