# Decorate: to_sort = [(item[1], item[3], item) for item in a_list] # Sort: to_sort.sort() # Undecorate: a_list = [item[-1] for item in to_sort] 上述代码第一行创建了一个tuple的list,tuple中的前两项是用来排序的字段,最后一项是原数据;第二行使用sort()方法对辅助的list进行默认...
代码如下 def selectionSort(x): i = 0 while i < len(x) - 1: minindex = i j = i + 1 while j < len(x) : if x[minindex] > x[j]: minindex = j j+= 1 if minindex != i: swap(x,i,minindex) i+= 1 return x 函数包括一个嵌套的循环,对于大小为n的列表,外围的循环执行n...
