Splitting a string

[Xavier Ho]

Oops, minor update:

>>> def split_number(string):
...     output = [string[0]]
...     for character in string[1:]:
...         if character.isdigit() != output[-1].isdigit():
...             if output[-1].isdigit() is True:
...                 output[-1] = int(output[-1])
...             output.append('')
...         output[-1] += character
...     return tuple(output)
...
>>> split_number('si_pos_99_rep_1_0.ita')
('si_pos_', 99, '_rep_', 1, '_', 0, '.ita')


Cheers,
Xav
