sage.misc.defaults.variable_names tuple vs list

[Reimundo Heluani]

The output of sage.misc.defaults.variable_names and latex_variable_names is of
type list if n=1 while type tuple if n>1. Is this really the intended
behaviour?

To concatenate another tuple/list to this output in a manner that is independent of n
requires an extra conversion.

Cheers,

R.

I would find that hard to believe. My guess the author forgot that a 1-element-tuple in python is spelled "(name,)" and hence found a list easier to return. It's also a routine that doesn't have a docstring or doctests!

I'd think "tuple" is the more appropriate thing to return here.

Thanks, I opened #29797

I don't think my patchbot can test it cause I switched to gcc 10.1 and I will
need to either change the Makefile or compile gcc as an SPKG.
