[Python练习题 026] 求100以内的素数. ------------------------------------------------- 奇怪,求解素数的题,之前不是做过了吗?难道是想让我用点新技能.比如 map() 之类的?可是我想了半天还是没想出来啊!只好还是用土办法.代码如下: p = [i for i in range(2,100)] #建立2-99的列表 for i in range(3,100): #1和2都不用判断,从3开始 for j in range(2, i)…
[本文出自天外归云的博客园] 题1:求m以内的素数(m>2) def find_all_primes_in(m): def prime(num): for i in range(2, num): if divmod(num, i)[1] == 0: return False return True print([i for i in range(2, m + 1) if prime(i)]) if __name__ == '__main__': find_all_primes_in(100) 我…
python求100以内素数之和 from math import sqrt # 使用isPrime函数 def isPrime(n): if n <= 1: return False for i in range(2, int(sqrt(n)) + 1): if n % i == 0: return False return True count = 0 for i in range(101): if isPrime(i): count += i print(count) # 单行程序扫描素数…
