python - simpler implementation of this string splitting loop -

i have function receives string dot delimited. want loop through value building , running code each level. here implementation:

def example(name):     module = []     in name.split('.'):         module.append(i)         print '.'.join(module)         #do stuff here

output

>>> example('a.b.c.d') a.b a.b.c a.b.c.d

but feels long winded. i'm looking simpler, cleaner or shorter implementation.

split once, slice it:

s = 'a.b.c.d'  items = s.split('.') print [items[:i] in xrange(1, len(items) + 1)] # [['a'], ['a', 'b'], ['a', 'b', 'c'], ['a', 'b', 'c', 'd']]
