list and for

[Breex]

I'm new at python programing i read some basic and i have a question. Probably it is easy but i dont know how to do it. (im looking for answer for 2 days)

I have something like this

string="awesome cat";
str=string.split();

for i in str:
    print ('-'.join(i));

And if i print it i have
a-w-e-s-o-m-e
c-a-t

And my question is how i make each i into new string like this "a-w-e-s-o-m-e c-a-t"?

I know its easy but im very basic at programing so im sorry if i hurt anyone with my question.
