Exposed get_base and get_exp functions - #1980

@isuruf Not sure why some tests fail here. Everything passes for me locally!
Am I missing some flag while building the project through cmake ?

This can already be achieved by using basic_get_args right?

Yes, I missed this. I've made the change.

No, I mean a user could use that method already in the C wrapper and I don't see why we'd need another method to do something similar.

Okay for some context, Ondrej and I would be adding support for some methods through the Cwrapper for addressing this TODO lcompilers/lpython#2332
We are trying to port some functionalities like the ones we could have through SymPy using Lpython (like expr.base and expr.exp) so that we could essentially support some modules like series through Lpython. Yeah I agree we could use the .args method but this is just so that we could introduce some consistency with SymPy.

Also could you educate me regarding the failing tests ?
When I run ctests locally everything works as required .

I think we should be designing the Symbolic API to be consistent, and I think we have done a lot of this work in SymEngine already. In particular, I think it's cleaner to access the arguments using .args, so I would just use that.

Regarding the failing tests, not sure what is causing it, you would need to debug it locally.

I think we can close this one. If you think we need it, you can reopen it.

Sure if we can do without creating these then let's try it out. I just thought of introducing some consistency with sympy but I think we can do without it !

LPython adds the consistency with SymPy. In SymEngine I think we should strive for a minimal C++ and C API, without duplication.
