I'm a nut for regular expressions and obfuscation...

import re
def splitline(line, size=4):
     return re.findall(r'.{%d}' % size, line)

 >>> splitline("helloiamsuperman")
['hell', 'oiam', 'supe', 'rman']


or if you care about remainders...

import re
def splitline(line, size=4):
     return re.findall(r'.{%d}|.+$' % size, line)

 >>> splitline("helloiamsupermansd")
['hell', 'oiam', 'supe', 'rman', 'sd']


noah
