What I want is :
If 11 & 12 standard is inputted then output is according to value of 'y' and if anything except 11 & 12 is given then I want the existing output which is being currently outputted in every condition

Answer 1

"if (not x == 12 or not x == 11)" is always True. If x is 12, "not x == 11" is True and the whole expression is True. Same if x is 11. If x is neither 11 nor 12, "not x == 12" is also True and the whole expression is True again. If you want to check if x is neither 11 nor 12, use "if x != 11 and x != 12" or "if x not in (11, 12)".
