Why Eval And Exec Are The WORST Python Functions [Tech Rants] 

The risk is when you let others use software you write ;)

@@CodingLikeMad I know, I was just kidding. Like you said, the greater the power the more responsible you have to be. It's not the tools' fault, it's how you use them.

Yeah, 100%. I guess the question is how trustworthy are people. I like people, but do I trust them? Mmm, not so much :p

On a side note, I too can use su. I once deleted most of /bin before realizing I was not where I thought I was when I used rm -rf :/

@@CodingLikeMad Lol, it would be even more tragic if you really wanted or needed to do that but instead you got an error message saying - "Permission denied. User root not trusted. Too irresponsible!".

The point is that you need to think of EVERY such word. Solving one is easy. Good luck catching them all.

Yeah, I also thought the same. What's the issue with that ?

I cannot think of an easy way to break that. But in that case, why not just make a list of options available? The issue is when free form code is allowed, and getting the benefits of that without insecurity is the problem. I would argue that in doing that comparison, you've basically made it totally pointless to do in the first place - it's just a more convoluted input system.
