I think you meant "usable" ;). Some of this results from Python's
statement-vs-expression distinction. I'm not going to claim that's a
broken feature of Python, since it has its supporters; but languages
that don't make the distinction have more flexibility in implementing
such features as ordinary functions rather than syntax features.
Ruby: 17.times| code |
Haskell: replicateM_ 17 code
Lisp: (dotimes (i 17) code...)
etc.
The Lisp example binds 'i' to the loop index, but that's just a choice
made in how the dotimes macro was implemented. The scope of i is
limited to the dotimes construct, unlike in Python.
