You can convert the numbers to a single string with

 >>> print(" ".join(str(i) for i in range(6)))
0 1 2 3 4 5

The argument of "".join() is called "generator expression".

Or you can use the star operator:

>>> print(*range(6))
0 1 2 3 4 5

This passes the elements of the range() iterable as individual arguments 
to print(), i. e. it's equivalent to

print(0, 1, 2, 3, 4, 5)
