subprocess.Popen

[jenya56]

I was wondering if any of you know of the way to pass multiple parameters into subprocess.Popen.
In the code below, I pass str(my_var). Is there a way to do something like str(my_var_1), str(my_var_2)?
Thank you so much! This forum is awesome!

item = subprocess.Popen(["batch_test_python_petrel_saving_Nexus.bat", str(my_var)] , 
                         shell=True, stdout=subprocess.PIPE)

Use shell=False when the first argument is a list.

Hi, thank you for your reply. I then use batch file and assign my variables which was not a problem with a single variable being passed in. Inside my batch, I did it like this:
@echo off
set arg1=%1
set /a vari=%arg1%
However, now I am not certain how to do what is above as I have multiple variables.
Any suggestions?

If I understand your question well, you want to know how to handle command line parameters in a batch script. I can't answer this because it is not a question about python. Why don't you write a python script instead of a batch script? Python can handle command line parameters very easily with the argparse module.
