Reading a gnuplot file from a Python script

Question

I am trying to run my gnuplot commands from a Python script. I came across a suggestion that I can save all the gnuplot commands in a file (with format codes for the variables I need to drop in) and then just read that file in with Python and format it. However, I couldn't find any examples to understand how it's done. Can somebody help me out?

PS: I am using gnuplot version 4.2 and I have already tried using -e pipe but for some reason it doesn't work. PPS: I would prefer not to use Gnuplot-py package

I would prefer not to use the Gnuplot-py package. Is there any alternate way? — user3262537

A simple example: Start with a text file with formatting codes,

The {adjective1} {adjective2} {mammal1} has escaped!

Then in Python you can substitute values like so:

# load the template
with open("template.txt") as inf:
    template = inf.read()

# substitute values
result = template.format(
    adjective1 = "lazy",
    adjective2 = "brown",
    mammal1    = "bear"
)

# save the result
with open("plot.dem", "w") as outf:
    outf.write(result)

The plot.dem file now contains

The lazy brown bear has escaped!
