How to inherit?

[sophiekovalevsky]

I'm trying to inherit spidev library to a custom class. I'm using python2.

This is the code that I'm using:
self.spi = spidev.SpiDev()
self.spi.open(bus,CS)
self.spi.mode = 0
self.spi.lsbfirst = False
self.spi.max_speed_hz = speed

And its tell me that global name 'spi' is not defined. Any suggestions?

I finally set up, using:
class Classname(spidev.SpiDev):

Hello!
I belive that the best way to inherit is in the class definition

import spidev
class MySpiDev(spidev.SpiDev):
    def __init__(self, *args, **kwargs):
        super(MySpiDev, self).__init__(*args, **kwargs) # python 2
        super().__init__(*args, **kwargs) # python 3
        self.open(bus, CS)
        self.mode = 0
        ...
