And we really mean it. There are two ways. One involves e**l, which means you are executing arbitrary code, and if a contained some malicious code, it could break your system. Using e**l is considered bad for this precise reason: you don’t know if the input might lead to formatting your hard drive. And you should not trust it to be good. The other way involves modifying the g*****s() dict. It does not always work though. But for a REAL way to do it, just create a dict and use it — you can have arbitrary variable names just fine: things = {} a = "aabb" things[a] = [] PS. why are you creating a out of two strings? Why not just a = "aabb"? -- Chris Warrick <https://chriswarrick.com/> PGP: 5EAAEA16 _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
