I would like to understand what I am doing wrong?
What is the way to close properly the driver?
Can you help me please?

Answer 1

Step1: you should get the appium session dictionary first:
session_instance = webdriver.Remote(str(url), caps_dic)
where url is your appium server url. something like: "http://127.0.0.1:4723/wd/hub"
and caps_dic is a dictionary of all your desired capabilities
Step2: you run the quit() method on session:
session_instance[session].quit()
So the whole snippet is:
session_instance = webdriver.Remote(str(url), caps_dic)
session_instance[session].quit()
