python学习之排序算法(选择排序和冒泡排序)

def selectSort(arr):
	for x in range(len(arr)):
		for y in range(x, len(arr)):
			if arr[x] < arr[y]:
				arr[x],arr[y]=arr[y],arr[x];
	return arr;

def bubbleSort(arr):
	for i in range(len(arr)-1):
		for j in range(len(arr)-i-1):
			if arr[j] > arr[j+1]:
				arr[j],arr[j+1]=arr[j+1],arr[j]

list = [1,5,3,23,4];
bubbleSort(list);
for x in range(len(list)):
	print(x, list[x]);
