I have a list that has some chapter numbers in string. When I sort the keys using keys function, it gives me wrong results.
keys = ['1.1', '1.2', '2.1', '10.1'] keys.sort() print keys ['1.1', '1.2', '10.1', '2.1']
How can I use the sort function to get
['1.1', '1.2', '2.1', '10.1']
What if the array has something like this?
['1.1.1', '1.2.1', '10.1', '2.1'] -> ['1.1.1','1.2.1','2.1','10.1']
