Python中使用插入排序算法的简单分析与代码示例

def insertion_sort(n):
 if len(n) == 1:
  return n
 b = insertion_sort(n[1:])
 m = len(b)
 for i in range(m):
  if n[0] <= b[i]:
   return b[:i]+[n[0]]+b[i:]
 return b + [n[0]]

def insertion_sort(lst):
 if len(lst) == 1:
  return lst

 for i in xrange(1, len(lst)):
  temp = lst[i]
  j = i - 1
  while j >= 0 and temp < lst[j]:
   lst[j + 1] = lst[j]
   j -= 1
  lst[j + 1] = temp
 return lst
