本文实例讲述了Python基于递归和非递归算法求两个数最大公约数、最小公倍数。分享给大家供大家参考,具体如下:
最大公约数和最小公倍数的概念大家都很熟悉了,在这里就不多说了,今天这个是因为做题的时候遇到了所以就写下来作为记录,也希望帮到别人,下面是代码:

#!/usr/bin/env python #coding:utf-8 from fractions import gcd #非递归实现 def gcd_test_one(a, b): if a! = 0 and b! = 0 : if a>b: a, b = b, a if b % a = = 0 : return a gcd_list = [] for i in range ( 1 ,a): if b % i = = 0 and a % i = = 0 : gcd_list.append(i) return max (gcd_list) else : print 'Number is wrong!!!' #递归实现 def gcd_test_two(a, b): if a>b: a, b = b, a if b % a = = 0 : return a else : return gcd_test_two(a,b % a) #python自带的gcd def gcd_test_three(a, b): return gcd(a,b) if __name__ = = '__main__' : print gcd_test_one( 12 , 24 ) print gcd_test_one( 12 , 8 ) print gcd_test_one( 6 , 24 ) print gcd_test_one( 0 , 24 ) print '----------------------------------------------------------------------------' print gcd_test_two( 12 , 24 ) print gcd_test_two( 12 , 8 ) print gcd_test_two( 6 , 32 ) print '----------------------------------------------------------------------------' print gcd_test_three( 12 , 24 ) print gcd_test_three( 12 , 8 ) |
结果如下:
12
4
6
Number is wrong!!!
None
----------------------------------------------------------------------------
12

2
----------------------------------------------------------------------------
12
4
希望本文所述对大家Python程序设计有所帮助。
