Python 逻辑代码：AND、NAND、OR、NOR、XOR、XNOR 和 NOT 模拟

Question

我试图找出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大门为例。当我运行代码并作为和 的1值传入时，输出仍然是。我尝试过调整它，它仍然给我作为输出。ABFalseFalse

以下是我迄今为止所做的示例：

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)

我还尝试将andand之间的and 替换为 an ，这似乎可行，但与and门重复使用有点困难：aInputbInputorXORXNOR

#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)

正如评论中所讨论的，尝试使用elif. 欢迎来到堆栈溢出！

#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)
