And he's right again. I should've checked for that. Well, that makes a
CmpInt class the only other solution:
class CmpInt(int):
def __lt__(self, other):

Here is my solution for the general case:
from itertools import groupby
def alphanum_key(string):
t = []
for isdigit, group in groupby(string, str.isdigit):
group = ''.join(group)
t.append(int(group) if isdigit else group)
return t
Note
fore 'a2'.
now with alphanumeric sort:
>>> a.sort(key=alphanum_key)
>>> a
['0a', '1a', '10a', 'a1', 'a2', 'a10', 'a11', 'b2', 'b3', 'b20']

Interesting. Can this also be used to make sorting of alphanumerical list items
in a 'numerical' way easier? E.g.:
x
['var_0', 'var_13', 'var_11', 'var_9', 'var_4', 'var_1', 'var_5', 'var_6',
'var_7', 'var_14', 'var_2', 'var_3', 'var_8', 'var_10', 'var_12'
are zfilled versions of the list items (e.g.
var_01, etc), then sort the keys, get the dictionary values in the right order,
etc. It seemed a cumbersome way. Isn't there an easier way to sort x?
Cheers!!

Hi,there:
The document of
Python.org[http://docs.python.org/library/stdtypes.html] says that:
--
s.sort([cmp[, key[, reverse]]])
8. The sort() method takes optional arguments fo
15 matches
