I am relatively new to Pyton and am trying to use a library called pyftdi

I have
been able to install the library and write a simple piece of code to

code seems
to work to accomplish that:
#!/usr/bin/python
from pyftdi.pyftdi.ftdi import *
vps=[(0x0403,0x6014)]
devs=Ftdi.find_all(vps)
print devs
However I cannot figure out what to do next.
If you are talking about this library:
http://pypi.python.org/pypi/pyftdi
have you tried reading the documentation, such as it is? I've had a
quick look, and it appears to be extremely light on documentation, but I
didn't dig too deeply, maybe you will have better luck. The GitHub page
claims to have some examples, but I couldn't get it to work in my browser.
You can also try this at the Python interactive interpreter:
import pyftdi
help(pyftdi)
and see if the library has any useful embedded documentation. It may not.
Do you know how to start the interactive interpreter? You need to open a
terminal window, then at the prompt, you need to launch Python. Under
Linux, I just type
python
and hit the ENTER key. If you are using Windows, it may be more
complicated.
Just the same for Windows, although I tend to use PythonWin myself.
