19 拿来就用的排序函数
排序：
In [1]: a = [1,4,2,3,1]
In [2]: sorted(a,reverse=True)
Out[2]: [4, 3, 2, 1, 1]
In [3]: a = [{'name':'xiaoming','age':18,'gender':'male'},{'name':'
...: xiaohong','age':20,'gender':'female'}]
In [4]: sorted(a,key=lambda x: x['age'],reverse=False)
Out[4]:
[{'name': 'xiaoming', 'age': 18, 'gender': 'male'},
{'name': 'xiaohong', 'age': 20, 'gender': 'female'}]
