Hi all, I am a Python novice, and right now I would be happy to simply get my job done with it, but I could appreciate some thoughts on the issue below. I need to assign one of four numbers to names in a list. The assignment should be pseudo-random: no pattern whatsoever, but deterministic, reprod

Executing untrusted code

Greetings everybody, I've been reading and mulling about python and security, specifically in terms of executing code that may or may not be trustworthy. I understand that libraries such as Rexec and Bastion are now deprecated because they have known vulnerabilities that may be exploited to circum
