python实现的希尔排序算法实例

本文实例讲述了python实现希尔排序算法的方法。分享给大家供大家参考。具体如下：

    def shellSort(items):
      inc = len(items) / 2
      while inc:
        for i in xrange(len(items)):
          j = i
          temp = items[i]
          while j >= inc and items[j-inc] > temp:
            items[j] = items[j - inc]
            j -= inc
          items[j] = temp
        inc = inc/2 if inc/2 else (0 if inc==1 else 1)
    a = [35, -8, 11, 1, 68, 0, 3];
    shellSort(a)
    print a # [-8, 0, 1, 3, 11, 35, 68]

希望本文所述对大家的Python程序设计有所帮助。
