Did you ever get this figured out? I'm trying the same thing and having lots of issues. Got any advice?

but I don't know if it possible to connect python with arduino wifi ?

The WiFi shield lets you connect wirelessly to a server, or to act as a server. Which role is the Arduino going to perform? Seem like it is going to be a server, serving up responses to GET requests (GET turningRight, GET going, GET stopped, GET faster, GET slower, etc.).

As a client, it does not know how the GET request arrived - from a PHP script, from a Python script, from an ASP.NET program, etc.

So, it isn't clear what your problem is. The type of scripting language on the server is NOT the problem, though.
