AND logic gate code:

The AND logic gate prints an output of 1 if both input operands are 1.

Operation:

def AND (a, b):
 
    if a == 0 and b == 0:
        return False
    else:
        return True
        
    if a == 1 and b == 0:
        return False
    else:
        return True
    
    if a == 0 and b == 1:
        return False
    else:
        return True
        
    if a == 1 and b == 1:
        return True
    else:
        return False
        
if __name__=='__main__':
    print(AND(1, 1))

Truth table:

+-----+-----+---------+
|  A  |  B  |  Output |
|-----+-----+---------|
|  0  |  0  |    0    |
|  1  |  0  |    0    |
|  0  |  1  |    0    |
|  1  |  1  |    1    |

OR logic gate code:

The OR logic gate prints an output of 1 if either input operands are 1. This gate also prints an output of 1 when both input operands are 1.

Operation:

def AND (a, b):
 
    if a == 0 and b == 0:
        return False
    else:
        return True
        
    if a == 1 and b == 0:
        return True
    else:
        return False
    
    if a == 0 and b == 1:
        return True
    else:
        return False
        
    if a == 1 and b == 1:
        return True
    else:
        return False
        
if __name__=='__main__':
    print(AND(1, 1))

Truth table:

+-----+-----+---------+
|  A  |  B  |  Output |
|-----+-----+---------|
|  0  |  0  |    0    |
|  1  |  0  |    1    |
|  0  |  1  |    1    |
|  1  |  1  |    1    |

NAND logic gate code:

The AND logic gate prints an output of 0 if both input operands are 1.

Operation:

    if a == 0 and b == 0:
        return True
    else:
        return False
        
    if a == 1 and b == 0:
        return True
    else:
        return False
    
    if a == 0 and b == 1:
        return True
    else:
        return False
        
    if a == 1 and b == 1:
        return False
    else:
        return True
        
if __name__=='__main__':
    print(AND(1, 1))
