Python: ZSYS module (mimics SYS)

[StephenG1CMZ]

Version 0.1 of ZSYS identifies calculator makers.
(Specific calculators cannot generally be identified).

Code:



"""ZSYS mimics part of sys where needed.

It allows portable code to identify calculator platforms despite most calculators not having sys.

Note: Since Python has yet to reach HP Prime Android, it is currently tested only on Numworks.
Update 2024: It fails to run on HP Prime!
