Physics Fun with Python Play
Using Python Play is seriously so much fun. In like 40 lines of code I wrote this fun little program with physics.
Click anywhere to create a ball.
Click and drag any ball anywhere.
Press Z to knock them all up in the air!
If you haven't tried using Python Play, I definitely recommend it.
If you spawn balls and dont move your mouse in the process, they will balance on each other LOL
I guess Python Play requires a specific type of Python-based REPL as it uses
async features of Python 3.7 but the standard Python 3 REPL has 3.6.x, right?
@PaoloAmoroso Python Play does use the asyncio features of Python 3.
await were added in Python 3.5 (source) so you just need a version of Python greater than that (which repl.it has). If you want to use Python Play on repl.it, you just need to use a Python (3) repl and install replit-play in the package manager. Or you can just fork this repl.
And the reason for using async/await is mostly to be able to set up timers. In normal loop-based python programming, it's really annoying (especially for beginners) to make a program that changes the background to red, waits 1 second, changes to green, waits 1 second, then changes to blue and cycles back to red. In Python Play you can just do that like this:
@play.repeat_forever async def do(): play.set_backdrop('red') await play.timer(seconds=1) play.set_backdrop('green') await play.timer(seconds=1) play.set_backdrop('blue') await play.timer(seconds=1)
