Linkit 7688 analogRead in python

[Boki0130]

I used a linkit 7688 duo to read a analog input with Arduino IDE in c code. But now I have the problems on transferring C to Python .I have already tried:
(1). import analogio ,but I cannot install it by typing even I tried first.
(2). import mraa. But I don't know what is the ADC pin mode in GPIO.

please help me, thanks !
