Yet Another Calculator using wxPython, smaller, but more advanced than the previous one. Wrote this one to test the Curry class, but it didn't work well. So there is no curry there. I found out that one has to be careful with the eval() function. If you write 012 instead of 12, it looks at 012 as an octal number with a denary value of 10. A few safeguards are included.
As you look at the code, you will see that most of it is simple copy and paste with minor modifications. I have added a power button, so you can do square roots like 25**0.5, which should give you a 5.0. Well, enjoy what's there, and improve on it!
