ImageMagick bash command from python script

Question

So I have this command:

PS C:\Users\lucas\OneDrive\Documents\3D\OpenRCT2\HotdogCycles> magick.exe test.png -fill 'sRGB(57,59,57)' -draw 'color 0,0 floodfill' mask_test2.png

Which is running perfectly fine. I need it to be run from a python script. So for testing, I open a python shell in the same directory and run the same command.

PS C:\Users\lucas\OneDrive\Documents\3D\OpenRCT2\HotdogCycles> python
Python 3.8.2 (tags/v3.8.2:7b3ab59, Feb 25 2020, 22:45:29) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.run("magick.exe test.png -fill \'sRGB(57,59,57)\' -draw \'color 0,0 floodfill\' mask_test2.png")
magick.exe: unable to open image ''sRGB(57,59,57)'': No such file or directory @ error/blob.c/OpenBlob/3537.
magick.exe: no decode delegate for this image format `' @ error/constitute.c/ReadImage/562.
CompletedProcess(args="magick.exe test.png -fill 'sRGB(57,59,57)' -draw 'color 0,0 floodfill' mask_test2.png", returncode=1)
>>>

If anyone can pinpoint how to get around this issue, this would be very welcomed!

EDIT - Debugging message (had no idea there was such a thing)

>>> subprocess.run("magick.exe test.png -debug All -fill \'sRGB(57,59,57)\' -draw \'color 0,0 floodfill\' mask_test2.png"
... )

You've got the string escaping wrong. Try this:

>>> subprocess.run("magick.exe test.png -fill 'sRGB(57,59,57)' -draw 'color 0,0 floodfill' mask_test2.png")

Note that I removed the back-slashes from \'sRGB(57,59,57)\' to sRGB(57,59,57)', likewise in the -draw argument.

Also splitting the command to a list could help:

>>> subprocess.run(["/usr/bin/convert", "test.png", "-fill", "sRGB(57,59,57)", "-draw", "color 0,0 floodfill", "mask_test2.png"])

I user convert rather than magick.exe as I'm on Linux, but the idea is the same.

I've noticed that I could reproduce the same bug in command prompt. The powershell is the only way I can make it work.

@lucas92 Added another method - split the args into a list. Works for me.
