拆分和映射到整数的键：
sorted(inputlist, key=lambda v: [int(i) for i in v.rstrip('@').split('.')])
这产生每一行整数列表，而这些都是然后按字典顺序排序;例如在不同的第一个元素上。
演示：
>>> sample = '''\
... [email protected]@
... [email protected]@
... [email protected]@
... [email protected]@
... [email protected]@

... [email protected]@
... [email protected]@
... [email protected]@
... '''.splitlines()
>>> from pprint import pprint
>>> sorted(sample, key=lambda v: [int(i) for i in v.rstrip('@').split('.')])

会'键=拉姆达X：浮子（x.rstrip（ “@”））'是整数的列表中的可接受的替代？ – inspectorG4dget 2014-09-24 09:35:16
@ inspectorG4dget：不，因为这里有3个组件的数字，它们不是有效的浮点数。 – 2014-09-24 09:36:00
当我在代码中尝试时，它抛出“ValueError：int（）与基数为10的无效文字：'\ x02'”@MartijinPieters – Nijesh 2014-09-24 10:10:26
