dear ferrters,

So, I am using python. There is a ferret.jnl script that needs to be run inside a python script.

you may ask, why?  The answer is, file handing(i.e, data variables and attributes ) is quite good in ferret, while python has its own upsides.

If there is any such way to do that, I would be glad to hear about it.

I'm sure there are a lot of more knowledgeable people about python than me, but . . . 

First of all, I'll assume you can run your ferret script, ferret.jnl, on the terminal (command line) as

pyferret -script ferret.jnl

Then, from within your python program, you do the same:

os.system("pyferret -script ferret.jnl")

or

import subprocess

subprocess.run(["pyferret", "-script", "ferret.jnl"])

See

I'm sure there are ways to directly call Ferret's functionalities from within python without going through a ferret script (ferret.jnl).

Best regards,

Ryo
