oops. my bad. here's a fixed version:
result = []; pos = 0
try:
while 1:
pos = mystring.index(substr, pos)
result.append(pos)
pos += len(substr)
except ValueError:
pass # done
or, if you prefer the generator variant:
def finditer(string, substr):
pos = 0
index = string.index
try:
while 1:
pos = index(substr, pos)
yield pos
pos += len(substr)
except ValueError:
pass # done
</F>
