There's also a gotcha with default parameters:

def fun(a = []):
    a += [1]
    return a

fun()
print(fun()) # [1, 1]

issues I had with the tool you linked

I tried to make a link to this code in this visual debugger, but a link is made broken and can't be used without urlencoding spaces (I guess). Also the tool doesn't produce visual output in DuckDuckGo browser on Android

You can just write your code and then press "Get URL" to get the link: https://memory-graph.com/#code=def+fun%28a+%3D+%5B%5D%29%3A%0A++++a+%2B%3D+%5B1%5D%0A++++return+a%0A%0Afun%28%29%0Aprint%28fun%28%29%29+%23+%5B1%2C+1%5D

DuckDuckGo problem, thanks for reporting.

Yeah, I wrote code and pressed get URL, but then I copied what was shown in the window

The clipboard content:

https://memory-graph.com/#code=+%23+What+is%2Bthe+output+of+this+Python+program%3F%0A+++%0Adef+fun%28a+%3D+%5B%5D%29%3A+%0A++++a+%2B%3D+%5B1%5D%0A++++return+a%0Afun%28%29+print%28fun%28%29%29

The window text:

The following URL has been copied to your clipboard with:

    The current code
    Set breakpoints
    Playback timestep
    Play/Pause state

https://memory-graph.com/#code=+%23+What+is+the+output+of+this+Python+program? +++ def+fun(a+=+[]):+ ++++a++=+[1] ++++return+a fun()+print(fun())

The latter doesn't work, and I didn't think of checking the former
