I make no claims of this being the best approach:
====================
def findOccurances(a_string, word):
"""
Given a string and a word, returns a double:
[0] = count [1] = list of indexes where word occurs
"""
import re
count = 0
indexes = []
start = 0 # offset for successive passes
pattern = re.compile(r'\b%s\b' % word, re.I)
while True:
match = pattern.search(a_string)
if not match: break
count += 1;
indexes.append(match.start() + start)
start += match.end()
a_string = a_string[match.end():]
return (count, indexes)
====================
Seems to work for me. No guarantees.
