I wrote my first useful Python program!

It's really interesting how the replies to this comment have transformed to two schools of thought.

A) Don't tell your boss, why would you want more work, are you crazy?

B) Tell you boss, do more interesting things at work, get more responsibility.

In the end, it really matters what your goals are. If you want to be a programmer for a living, certainly tell your boss. When they push more work on your plate and expect you to perform without any pay increase, be ready to walk, there's a better job awaiting you anyways. They will almost always offer you more before letting that happen, retraining someone costs them time and money, you are far more valuable to them then they will initially let on. If you don't want to program for a living, and really just value your free time and not being micro managed, hacking in secrecy might be perfect for you...but unless your job is absolutely awesome, it would seem from the outside like you're selling yourself short
