Python suprocess.run() for Windows

Question

I create a png file and view it on macOS with

[...]
image.save("mandel.png", "PNG")
p = subprocess.run(["open", "mandel.png"], capture_output=True)
print(p.stdout.decode(),p.stderr.decode())

But what have I to choose for windows? "open" doesn't work on Win10.

Answer 1

[...]
image.save("mandel.png", "PNG")
p = subprocess.run(["start", "mandel.png"], capture_output=True)
print(p.stdout.decode(),p.stderr.decode())

You can use the start command in windows.
