self = 1

arr = {1,2,3,4,5,6}

if ( self != 1) and ( self != 2)  : print self, 'is not 1 and 2'

if ( self == 1) or  ( self == 2)  : print self, 'is Either 1 or 2'

else: print "not present"

if ( self in arr) : print self,'self is in arr'

if ( self not in arr)  : print  self, 'self is not in arr'

if ( self is not 2) : print self,'Yes self is not 2'

if ( self is 1 ) : print  self, 'yes self is 1.'

Using not in with if

if  0 not in (1,2) : print “zero present”

Using all and any

cond1 =2

cond2= 7

cond3=10

if  all( [ cond1 == 2, cond2 ==3, cond3 ==10] ):   print 'valid-All'

else:print 'invalid-All'

if  any( [ cond1 == 2 ,cond2 ==3, cond3 ==10] ): print 'valid-Any'

else:print 'invalid-Any'
