list and for - Breex - Jun-18-2018

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.

Hello!
s="awesome cat"
l=s.split()
out=[]
for s in l:
    out.append('-'.join(list(s)))
print(' '.join(out))

Just replace space with empty string

print('-'.join("awesome cat".replace(' ', '')))
and the output is 
Output:
a-w-e-s-o-m-e-c-a-t
str is Python built-in type/function, and giving names of built-ins to variables is potentially dangerous. Little demonstration 
Output:
In [1]: str(1)
Out[1]: '1'

In [2]: str = 's'

In [3]: str(1)
