[Tutor] Using Python to send signals to the USB port

[Jaidev Deshpande]

Hi

Is there some way I can use Python to send data through a USB port and
control the data in real-time?

(For instance, I can make a sinusoidal wave of a given specification, and
visualize it using NumPy / Matplotlib. How can I send the digitized form of
this array through a USB port, and then convert it back into analog so I can
view it on an oscilloscope?)

Thanks.
