For that particular string, I can think of 2 one-liners:

>>> s='100x150+25+25'
>>> print tuple([int(x) for x in s.replace('x', '+').split('+')])
(100, 150, 25, 25)
>>> print tuple([int(x) for y in s.split('x') for x in y.split('+')])
(100, 150, 25, 25)


For more general use, the regular expression "\d+" will match positive
integers:

>>> s='100x150+25+25/(34*7);12-34*(56%78/9)'
>>> import re
>>> print tuple([int(x) for x in re.findall('\d+', s)])
(100, 150, 25, 25, 34, 7, 12, 34, 56, 78, 9)
