Somehow you'll need to test each element in the string to know if it is an integer or not. You could do the str.isdigit() method or you could do something like this: temp = '' for i in yourString: try: int(i) temp += i except: pass Maybe someone knows of a parser. However, that will likely be more complex. Mike -- http://mail.python.org/mailman/listinfo/python-list
