Start px4_sitl_default jmavsim simulation from within Python Script

[Kathik-R]

Hello!

I have built a Pixhawk quadcopter with PX4 installed on it and I wish to create a virtual copy of it.
I have installed dronekit and dronekit-sitl on my Python3 (Ubuntu 20.04).
The PX4 Toolchain has been installed and it works as expected. When I use the terminal to launch a simulation using the command make px4_sitl_default jmavsim the virtual drone is created.
However, I want to do this through a python script. Is there a way to mimic the following terminal command in python using dronekit_sitl package?

I ran the following code but it creates an APM Copter V3.3.

connection_string = '127.0.0.1:14540'
try:
        #### connect to px4 drone if simulation already triggered
	vehicle = connect(connection_string, wait_ready=True)
except:
        #### trigger new px4 sitl jmavsim simulation
	import dronekit_sitl
	sitl = dronekit_sitl.start_default()
	vehicle = connect(sitl.connection_string(), wait_ready=True)

How can I give it the input to use px4_sitl_default and jmavsim instead of Arducopter?

Thank you for your time :)
