is python eval a security riski?

Question

A few years ago (on another form) it was recommended not to use javascripts' eval function as it posed a security risk, but I see it used quite often here in python codes. I assume it's OK to use it then (in python code)?

Answer 1

Combining it with input makes it dangerous and then stuff like this can happen:

Answer 2

I linked xkcd because all those "bad boys" can be rendered harmless by sanitizing the input.

Answer 3

Seems you can do harm against eval even with limited globals if you're tricky.

Answer 4

It safe your memory consumption. It is like a type casting, it is safe for us. Don't worry....
