how to simplify boolean logic in if else statement?

Question

I have 4 variables, some of them will be True and False, and for each combinations, i will have to call one or few functions. i am currently using a if else statement for ea

Answer 1

One way to simplify it would be to recognise and factor out the duplication:

if self.phone:
    if self.isp() == "east":
        self.launchbell()
    else:
        self.launchtelus()

if self.cpe_ip and self.cpe_passwd:
    print 'check modem...'
    self.modemstatus()

if self.pppoe:
    radius = sgp_radius.Radius(self.pppoe)
    print 'check radius logs...'
    self.data = radius.sgp()
    self.radius_save()
