[Tutor] sorting the list

[siddharth karandikar]

i have list like this
>>>a = ['a1', 'a2', 'a3', 'a4', 'a10', 'a11', 'a12']
>>>a
['a1', 'a2', 'a3', 'a4', 'a10', 'a11', 'a12']

when i call
>>>a.sort()

list becomes
>>>a
['a1', 'a10', 'a11', 'a12', 'a2', 'a3', 'a4']
**# here a10 is getting ahead of a2 a3 etc
>>>

but i need the list to be sorted like

a1 a2 a3 a4 ... a10 a11 etc.


any possible solution ???
