-1 for being ambiguous to newbies.  What would
that mean, start and zero and go until four?
Probably, but *I* read the previous thread on this.
If a newbie had just learned about Python's ability
to evaluate 0 <= i < 5 and return 1 or 0 for true/false
the above might be a little perplexing.  Is it like
for 1: if i is in that range, and for 0: if not?

Just in typing the above I had to hit backspace
three times to type it right.  May "look" nice
to some, but too obscure to others I think.
Why fix what doesn't need fixing?
