The world is crazy enough as it is. Please don’t argue, respect each other and each other’s achievements. Citing sources should go without saying: in that respect, the correction was appropriate from my perspective. The subsequent discussion was an unnecessary waste of time.
The PicoCalc is fantastic in its own right. I love using it, more for the sheer enjoyment of it, to quickly and directly program small “building physics” applications with MMBasic, for example. That’s perfectly sufficient for me: Python would only make sense if I could write the code directly on the PicoCalc. But of course, porting Python to the PicoCalc is quite an achievement.
Many websites on the internet contain code that isn’t properly cited: that’s not okay in itself… but for a simple program, such as making an LED blink or displaying “Hello World,” the possibilities for individual coding or… The solution is certainly more limited; a bit more flexibility would be welcome here 
All the best to everyone!
