You are out of luck, the softspace mechanism, roughly

softspace = False
for i in range(5):
    if softspace:
        print(end=" ")
    print(i, end="")
    softspace = True
print()

with `softspace` saved as a file attribute, is gone in Python3. But I don't 
think that someone who doesn't know it existed will miss the feature.

Maybe you can allow for /some/ magic and introduce your students to

print(*range(5))

early-on.
