Yes. There is a class called Del in sympy.vector.deloperator.py. But in current implementation, it does not return the del operator ( the grad operator). It only calculates gradient, curl and divergence.
Thank you for the suggestion. Even I was thinking returning a del operator from del class would be better. I'll incorporate that in my proposal. Thank you for reviewing my proposal.
