Sorting numbers in string format with Python
- by prosseek
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']
