Hello,
You can have a look at question #q374976, You can do so by using below code.
import os
from ament_index_python.packages import get_package_share_directory
from launch import LaunchDescription
from launch.actions import ExecuteProcess
from launch_ros.actions import Node
def generate_launch_description():
package_dir =get_package_share_directory('<package_path>') # add package path
world_files = os.path.join(package_dir,'worlds','<world_path>') # add world file path for *.world file
ld = LaunchDescription()
gazeboworld = ExecuteProcess(
cmd=['gazebo','--verbose',world_files,'-s','libgazebo_ros_factory.so']
)
ld.add_action(gazeboworld)
return ld

And Let's say you have URDF file and you want to add in Gazebo,
def generate_launch_description():
urdf = os.path.join(get_package_share_directory(
robot_name), 'urdf', '<File>.urdf')
xml = open(urdf, 'r').read()
xml = xml.replace('"', '\\"')
swpan_args = '{name: \"my_robot\", xml: \"' + xml + '\" }'
return LaunchDescription([
ExecuteProcess(
cmd=['gazebo', '--verbose', world,
'-s', 'libgazebo_ros_factory.so'],
output='screen'),
ExecuteProcess(
cmd=['ros2', 'service', 'call', '/spawn_entity',
'gazebo_msgs/SpawnEntity', swpan_args],
output='screen'),
])
