Re: [sumo-user] newbie to sumo
Have a look at my code and help me understand what am I doing wrong?

I am used to generating using .net.xml format and also with NETEDIT, but I don't understand how to edit a particular network scenario using Python, like adding a car to a network. That's what I'm looking for.

Please take a closer look at the tutorials. They contain links to example files.

Thanks for the response, it would be helpful if you could send me a sample project.

Hello, 
I am a fresher to SUMO. Can anyone tell me if I can control my SUMO simulation with my self-made python programs? If yes, can anyone send me a simple program?
