Our next gate is the AND gate. This gate receives two inputs and only returns current if the inputs are both on.

As in previous exercises, you’ll only be able to use gates you’ve previously built: NAND_gate(), and NOT_gate().

Here’s the truth table:

a b output
0 0 0
0 1 0
1 0 0
1 1 1



Define AND_gate() which has two parameters a and b.

AND_gate() should return 1 if both a and b are 1. It should return 0 otherwise.
