我正在试图找出为什么我的代码无效。为什么我的一些逻辑门,如OR,没有给我正确的输出?以OR门为例。当我运行代码并传递1作为AB的值时,输出仍为False。我试过调整它,它仍然给我False作为输出。

以下是我到目前为止所做的一个例子:

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and替换aInputbInput之间的or似乎有效,但有点难以重复使用{{1} }和XOR盖茨:

XNOR

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)

您可能也对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,这只会输出您的预期。

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
