```auto
def setup():
    size(500,500)

def draw():
    rect(100,100,100)

```

Today I bought a notebook, where I installed Processing,  
Java projects work fine, but for python I run the code and it immediately stops

Have you granted authorization for the Py Mode to access your LAN when the firewall window popped up? That’s all I can think about for now. 🙄

Just a detail: your `rect(100,100,100)` statement is missing the 4th argument (`height`). 😳

```auto
def setup():
    size(500, 500)

def draw():
    rect(100, 100, 100, 100)

```

Have you already explored the Python sketch examples to check if they work? Hit CTRL+SHIFT+O for it. 🐍

(I wish it was just the 4th statement the problem)  
Nope, examples dont run

I have not yet had a chance to see this happen; we had zero problems in-class on Thursday, but a number of problems manifested over the weekend. We are attempting to use Py.Processing. Perhaps it is not ready for prime-time? Either way, I know students have problems on Windows 10/64-bit, but I couldn’t possibly go further in…

I have been using Processing 3.3 with Processing.py in my classroom for quite a while with no problems. A student just brought in her MacBook Air, onto which she loaded Processing 3.4. We’re seeing the same Python mode behavior as mentioned above - when the program runs there’s no error message, no window display, nothing. The console area scrolls a little but nothing is displayed in it. Java mode seems to work. I see that the title of this message is marked SOLVED but I don’t see any solution posted.  
Thanks,  
Andy

I tried the downloaded connected to this solution but was met with a Mac error. Has anyone else experienced the same?
