Python 练习实例36
题目:求100之内的素数。
程序分析:无。
程序源代码:
#!/usr/bin/python # -*- coding: UTF-8 -*- from math import sqrt if __name__ == '__main__': N = 100 a = range(0,N) for i in range(2,int(sqrt(N))): for j in range(i + 1,N): if (a[i] != 0) and (a[j] != 0): if a[j] % a[i] == 0: a[j] = 0 print for i in range(2,N): if a[i] != 0: print "%5d" % a[i] if (i - 2) % 10 == 0: print
以上实例输出结果为:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
