Should calculators be able to read .txt files?

[StephenG1CMZ]

21st-century PC's have real problems handling compilable files, such as .py.
In the 20th Century it was trivial to rename a file, but not now.
If you cut-and-paste text, then ask Wordpad to save it as .py, it will pretend to do so.
In reality, it creates .py.txt.
Help says right-click/rename, but either help or pc is broken.

Given that creating a .py file on a PC seems utterly impossible, would it not make sense for calculators to handle reading and compiling .py.txt files, just like they can handle .py files.

I imagine this would avoid lots of problems in classrooms due to PC file formats being incompatible with calculators, which expect .py rather than .py.txt.

Platform: Windows PC and Casio CG50.
(Just to be clear, if you somehow create a .py file on the PC, it works - but most users will be unable to do so, even after years of PC experience)
