I’m using the [python package p5python package p5](https://github.com/p5py/p5)

I’m following some tutorials written in javascript, but it seems like push and pop is not the same in the python package.

I’m using the push\_matrix() and the pop\_matrix() function.  
As far as I understand this code shouldn’t do anything:

push()  
translate(x,y)  
pop()

Right? because there is nothing inside the push pop function.

But In this Python example:

```auto
translate(100,100)
pop_matrix()
circle((500,500),50)

```

The circle has moved to position 600,600. I thought it should be at 500,500.

Would love your input. Full code:

```auto
from p5 import *

def setup():
    size(1000, 1000)

def draw():
    background(255)
    fill(0)
    push_matrix()
    translate(100,100)
    pop_matrix()
    circle((500,500),50)

run()

```

According to the [documentation](https://p5.readthedocs.io/en/latest/guides/for-processing-users.html?highlight=push_matrix()#shapes-etc), this:

```auto
pushMatrix()
translate(width/2, height/2)
point(0, 0)
popMatrix()

```

becomes:

```auto
with push_matrix():
    translate(width/2, height/2)
    point(0, 0)

```

So in your case, you want something like this:

```auto
...

def draw():
    background(255)
    fill(0)

    with push_matrix():
        translate(100, 100)
        circle((500, 500), 50) # translated
    
    no_fill()
    circle((500, 500), 50) # centered

...

```
