The re module has s function "findall" that does what you want.
Also, if you read the documentation for strings find method, you'll find: 1 S.find(sub [,start [,end]]) -> int 2 3 Return the lowest index in S where substring sub is found, 4 such that sub is contained within s[start,end]. Optional 5 arguments start and end are interpreted as in slice notation. 6 7 Return -1 on failure. So put your find in a loop, starting the search one past the previously found occurrence. i = string.find(mystring, i+1) Gary Herron -- http://mail.python.org/mailman/listinfo/python-list
