Some related links:

• Python to FOCAL Compiler
• Python to RPN converter
  

And here's an example of disassembled byte code from Hy:



Which can then be translated to RPN/FOCAL:

Code:

LBL "CIRCLE"
STO 00 ; r
RDN
PI
RCL 00 ; r
2
Y↑X
*
RTN

Addendum: This is the result of the current version 1.0.0 in try-hy:

Code:

import hy
------------------------------
Hy 1.0.0 (Afternoon Review) using CPython(main) 3.12.1 on Emscripten
=> (import math [pi])
from math import pi
None
------------------------------
=> (defn circle [r] (* pi (** r 2)))
def circle(r):
    return pi * r ** 2
None
------------------------------
=> (import dis [dis])
from dis import dis
None
------------------------------
=> (dis circle)
dis(circle)
------------------------------
  1           0 RESUME                   0
              2 LOAD_GLOBAL              0 (pi)
             12 LOAD_FAST                0 (r)
             14 LOAD_CONST               1 (2)
             16 BINARY_OP                8 (**)
             20 BINARY_OP                5 (*)
             24 RETURN_VALUE

Conclusion: While the generated byte code for Python 3.12 is different it can still be easily translated to RPN/FOCAL.
