本文实例讲述了python排序方法。分享给大家供大家参考。具体如下：

>>> def my_key1(x):
...   return x % 10
...
>>> alist = [4, 5, 8, 1, 63, 8]
>>> alist
[4, 5, 8, 1, 63, 8]
>>> alist.sort() # 默认升序排序
>>> alist
[1, 4, 5, 8, 8, 63]
>>> alist.sort(reverse = True) # 改为降序排序
>>> alist
[63, 8, 8, 5, 4, 1]
>>> alist.sort(key = my_key1) # 设置排序的key值
>>> alist
[1, 63, 4, 5, 8, 8]
>>>
>>> def my_key2(x):
...   return x[1]
...
>>> alist = [(5,'a'),(1,'w'),(2,'e'),(6,'f')]
>>> alist.sort(key = my_key2) # 根据每个元组的第二分量进行排序
>>> alist
[(5, 'a'), (2, 'e'), (6, 'f'), (1, 'w')]
>>>
