==========
def getAllIndex(aString=None, aSub=None):
    t=dict()
    c=0
    ndx=0
    while True:
        try:
            ndx=aString.index(aSub, ndx)
            t[c]=ndx
            ndx += 1
            c += 1
        except ValueError:
            break
    return t
===========

This will return a dictionary of what was found; i.e.,

>>> getAllIndex('abcd 1234 efgh 1234 ijkl', '1234')
{0: 5, 1: 15}
