Hi @abhinov2

1. No, it is not safe in general. For Gamma, we do not care because it is running on Google's infrastructure, but this is still unsafe.
2. You would have to write a parser to replace sympify that does not use eval.

Hi @lidavidm Q1. Tell me one thing , this parser you talking about is for sympy or sympygamma ?

[lidavidm]

The parser would be for either. It does not exist (AFAIK, maybe SymPy has one now) and you would need to implement it.

Work in progress on this here https://github.com/sympy/sympy/pull/12524 (but I haven't worked on it in a while).
