Python Logic Code: AND, NAND, OR, NOR, XOR, XNOR, & NOT模拟

Question

我想弄清楚为什么我的代码不起作用。为什么我的一些逻辑门，例如 OR，没有给我正确的输出？以 OR 门为例。当我运行代码并传入 1 作为 A 和 B 的值时，输出仍然是 False。我试过调整它，它仍然给我 False 作为输出。

以下是我目前所做的示例：

aInput = int(input('Enter value for A: '))
bInput = int(input('Enter value for B: '))

#AND Gate
if aInput == 1 and bInput == 1:
    ANDGate = "True"
    ANDGateNum = 1
else:
    ANDGate = "False"
    ANDGateNum = 0

print('AND Gate output is', ANDGate, 'or', ANDGateNum)

#NAND Gate
if aInput == 1 and bInput == 1:
    NANDGate = "False"
    NANDGateNum = 0
else:
    NANDGate = "True"
    NANDGateNum = 1

print('NAND Gate output is', NANDGate, 'or', NANDGateNum)

#OR Gate
if aInput == 1 and bInput == 1:
    ORGate = "True"
    ORGateNum = 1
if aInput == 1 and bInput == 0:
    ORGate = "True"
    ORGateNum = 1
if aInput == 0 and bInput == 1:
    ORGate = "True"
    ORGateNum = 1
else:
    ORGate = "False"
    ORGateNum = 0

print('OR Gate output is', ORGate, 'or', ORGateNum)

#NOR Gate
if aInput == 1 and bInput == 1:
    NORGate = "False"
    NORGateNum = 0
if aInput == 1 and bInput == 0:
    NORGate = "False"
    NORGateNum = 0
if aInput == 0 and bInput == 1:
    NORGate = "False"
    NORGateNum = 0
else:
    NORGate = "True"
    NORGateNum = 1

print('NOR Gate output is', NORGate, 'or', NORGateNum)

#XNOR Gate
if aInput == 1 and bInput == 1:
    XNORGate = "True"
    XNORGateNum = 1
if aInput == 1 and bInput == 0:
    XNORGate = "False"
    XNORGateNum = 0
if aInput == 0 and bInput == 1:
    XNORGate = "False"
    XNORGateNum = 0
else:
    XNORGate = "True"
    XNORGateNum = 1

print('XNOR Gate output is', XNORGate, 'or', XNORGateNum)

#XOR Gate
if aInput == 1 and bInput == 1:
    XORGate = "False"
    XORGateNum = 0
if aInput == 1 and bInput == 0:
    XORGate = "True"
    XORGateNum = 1
if aInput == 0 and bInput == 1:
    XORGate = "True"
    XORGateNum = 1
else:
    XORGate = "False"
    XORGateNum = 0

print('XOR Gate output is', XORGate, 'or', XORGateNum)

#NOT Gate
if aInput == 1: 
    NOTGate = "False"
    NOTGateNum = 0

else:
    NOTGate = "True"
    NOTGateNum = 1

print('NOT Gate output is', NOTGate, 'or', NOTGateNum)

我还尝试用 or 替换 aInput 和 bInput 之间的 and ，这似乎有效，但有点难以重复使用 XOR 和 XNOR 门：

#OR Gate
if aInput == 1 or bInput == 1:
    ORGate = "True"
    ORGateNum = 1
else:
    ORGate = "False"
    ORGateNum = 0

print('OR Gate output is', ORGate, 'or', ORGateNum)

#NOR Gate
if aInput == 1 or bInput == 1:
    NORGate = "False"
    NORGateNum = 0
else:
    NORGate = "True"
    NORGateNum = 1

print('NOR Gate output is', NORGate, 'or', NORGateNum)

Answer 1

如评论中所述，请尝试使用 elif。欢迎来到 Stack Overflow！

#OR Gate  
if aInput == 1 and bInput == 1:  
    ORGate = "True"  
    ORGateNum = 1  
elif aInput == 1 and bInput == 0:  
    ORGate = "True"  
    ORGateNum = 1  
elif aInput == 0 and bInput == 1:  
    ORGate = "True"  
    ORGateNum = 1  
else:  
    ORGate = "False"  
    ORGateNum = 0  

print('OR Gate output is', ORGate, 'or', ORGateNum)

Answer 2

您可能还对 AND (&)、OR (|) 和 XOR (^) 的按位运算符感兴趣：

a = int(input('Enter value for A (0 or 1): '))
b = int(input('Enter value for B (0 or 1): '))

print("AND: ", bool(a & b))
print("OR:  ", bool(a | b))
print("XOR: ", bool(a ^ b))

如果用户输入 0 或 1，这只会输出您期望的内容。

Enter value for A (0 or 1): 1
Enter value for B (0 or 1): 1
AND:  True
OR:   True
XOR:  False

Enter value for A (0 or 1): 1
Enter value for B (0 or 1): 0
AND:  False
OR:   True
XOR:  True
