Python编程：求满足条件的分数个数

from math import *

def isprime(n): #判断一个数是否为素数 if n <= 1: return False for i in range(2, int(sqrt(n))+1): if n%i == 0: return False return True

def main(): a=int(input('please input a:')) b=int(input('please input b:')) if(a<=0 or b<=0 or a<=b): print('Input Error') else: ##以下为求出满足条件的分数的个数 count = 0 for n in range(10, 100): if isprime(n): for m in range(int(nb/a)+1, int(n6/a)): if isprime(m) and n!=m and 5m<=n6 and 6m>=5n: count += 1 print('满足条件的数有{:d}个'.format(count))

main() ##调用main函数实现程序的功能
