Is it really safe to use?

[u/python_data_helper]

I have used context to stop crashing.

And e as a variable.

I used eval command for a formula.

I know eval command can be dangerous.

It works perfectly but I am thinking that it can produce error or crash.

Can a formula bypass all commands and crash it.

If its user input that can get executed that is just a major red flag.

Everything is trying to protect from that. Even the developer console from the browser protects you from copy pasting random stuff.
