You need to be a bit more careful about explaining exactly what you want but
my guess is that you want to convert from whitespace delimited to ';'
delimited.  So something like:

x   = re.findall (r"('[^']*')|([0-9]+)", input_string)
res = ';'.join([a or b for a,b in x])

would do the trick.  This leaves the ' characters in, a little bit more work
could get rid of them too.
