Dear Folks, I want to execute a command from within python using the subprocess module.
Coming from a Perl background, I thought I could use variable interpolation in strings, but found that this is neither supported nor the Python way. Accordingly, I am a little at sea about how to accomplish it.
I have stated what I am trying to do in the minimal example below: --- import subprocess width = 5 height = 30 colors = ['#abcdef]', '#456789'] filename = "/tmp/image.png" # I want to get the equivalent of variable interpolation in Perl # so that the command # # convert -size 5x30 gradient:#abcdef-#456789 /tmp/image.png # # is derived from the variables above # and executed by subprocess.call() or subprocess.Popen() # from within Python # # Note that the command "convert" is from the ImageMagick suite # It exists and is executable by the shell; # the remaining values are arguments. # The command has been confirmed to execute correctly. --- Thanks in advance.
