Yes. To add new stuff to the language you would have to work at the
interpreter level. Probably you can avoid going too deep using import
hooks, as it has already been suggested, to modify what's

I'm trying to practice safe coding techniques. I just want to make sure that a

You can't sort a string, since it's immutable. You can, however, sort

Coding convention.

is faster, and if you calculate len before starting the

each iteration of each loop!)
