数据结构与算法历程

冒泡排序：
l = [9,4,8,7,6,4,7,2,0]
def bubble(li):
    l_len = len(li)
    print(l_len)
    for i in range(l_len-1,0,-1): # 注意这里的-1，递减1
        print('.')
        for j in range(0,i):
            temp = 0
            if li[j] > li[j+1]:
                temp = li[j]
                li[j] = li[j+1]
                li[j+1] = temp
                print(li)
    return li
print(bubble(l))

面试题：
给列表中的字典按照age排序

alist = [{'name':'a','age':13},{'name':'s','age':12},{'name':'d','age':11},{'name':'f','age':18},]

print(sorted(alist,key=lambda x:x['age']))
