It sounds like your intended use is as a hobbyist (?).


STFW for Arduino Uno R3:

https://store.arduino.cc/arduino-uno-rev3

Microcontroller 	ATmega328P

Flash Memory 	32 KB (ATmega328P) of which 0.5 KB used by bootloader

SRAM 	2 KB (ATmega328P)

EEPROM 	1 KB (ATmega328P)

Clock Speed 	16 MHz


STFW for the CPU:

http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-42735-8-bit-AVR-Microcontroller-ATmega328-328P_Datasheet.pdf

The Atmel® picoPower® ATmega328/P is a low-power CMOS 8-bit
microcontroller based on the AVR® enhanced RISC architecture.


STFW for embedded Python:

https://www.usenix.org/system/files/conference/atc12/atc12-final30.pdf

This  paper  presents  one  mechanism  for  doing  so:
an  efficient  embedded  Python  run-time  system  named
Owl. The Owl system is a complete Python development
toolchain and run-time system for microcontrollers that
do not have enough resources to run a real operating sys-
tem, but are still capable of running sophisticated soft-
ware systems.  These microcontrollers typically operate
at 50–100 MHz, have 64–128 KB of SRAM, and have
up  to  512  KB  of  on-chip  flash.


Note that the frequency, RAM, and ROM requirements for embedded Python 
exceed what is provided by the Arduino Uno.  So, that explains why I 
also find no solutions for Python on the Arduino Uno R3.


If you want an embedded kit that can do Python (2 or 3?), your best bet 
is to get a kit that supports Python OOTB:

https://wiki.python.org/moin/EmbeddedPython


Getting a kit that supports Linux OOTB would give you even more options:
