[Tutor] help with my python app

[james middendorff]

Hello, I would like to be able to use the arrow keys
to control a remote control car, which I can do but
only one key at a time. I would like to press the up
key, then while it is moving forward, press the left
or right key to turn while it is moving forward? I am
sure there are probably better ways to write the code,
I am still learning all of this. Also if this
indention is off I am including the file
thanks
