I know some people doing this!

Agreed, blue ducks are the worst!

What could possibly go wrong

Ive never had any reason tu even use eval. Can someone give me an example of when it might be useful? (even if its not safe)

@Codex404 for a plotter created in Python in 15 mins.
The text inserted by the user were inserted into a Function with only return "userformula".
Later with MatPlotLib the script will plot the function.
In the zone with eval are automatically included all the obj in math module

Never used eval

Cuz eval is evil 😈

@eisterman A friend of mine (beginner) wrote a Python script that calculated the derivative function of an function the user typed in. He showed it to me and I said: "You should not use eval()".
He: "Oh, ok. May you write a parser?"
I: "Wait! It's ok. Just use eval!"😂

@rhein7 exactly!
Only for speed :3
