Complex logic gate?

So I've made a Python module that adds all seven logic gates (NOT, OR, AND, NAND, NOR, XOR, XNOR.)

Please note that it does not look like

a AND b

it instead looks like

And(a, b)

In a program I'm trying to make, I need a logic gate with three inputs: A, B and C. the gate should return whatever A is if C is false. However, if C is true, it should return whatever B is. It does not matter if A and B are the same. I don't want to use actual if's.

If you are trying to create a multiplexer gate from the logic gates you have defined, here is a great article on the subject: http://improve.dk/creating-multiplexers-using-logic-gates/.

Basically, you do this:

def MUX(A, B, C):
    return OR(AND(A, C), AND(B, NOT(C)))

In Python notation, this would look like (A & C) | (B & ~C).

If C is True, the result is A. If C is False, the result is B.

Do you want this : here

Here you have your C instant of SEL. The out is your MULTIPLEXER return

so in python

def MULTIPLEXER(A,B,C):
   if(C):
      return B
   else:
      return A

Is this what you're looking for?

def MUX(A, B, C):
    return B if C else A
