Access to S constants directly eval(srepr(S.UniversalSet))

[latot]

Hi all, well as you know S have constants like Reals, UniversalSet, EmptySet, etc... I need some way to can use it directly (eval some str and get it), this is because srepr don't return the full expression:

from sympy import *

S.Reals

(-oo, oo)

srepr(S.Reals)

'Reals(-oo, oo, S.true, S.true)'

eval(srepr(S.Reals))

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "<string>", line 1, in <module>

NameError: name 'Reals' is not defined

Are some function to return the full expression? like 'S.Reals(-oo, oo, S.true, S.true)'

I'm not an expert in python, so this maybe can be fixed with an import, but i don't know which...

Thx. Cya.

This is a bug. Reals(-oo, oo, S.true, S.true) isn't actually correct. srepr(S.Reals) should be returning "S.Reals). See https://github.com/sympy/sympy/issues/10035.
