尝试重复我做的二进制加法器，但是我得到了缩进和无效语法等错误。有人看到和化学需氧量有关的问题吗

Question

print ("Input a binary number")

num1 = int(input() , 2)

print ("again prease")

num2 = int(input() , 2)

answer = num1 + num2

binaryanswer = bin(answer)[2:]

print ("That's " ,binaryanswer, " In behhieerryy")

input ("Press enter to end Program")          

again = raw_input

if again == 'Y':
    print("AGAAAINN!!")
    return

else:
    break

每件事都做得很好，但我能让程序重复它自己。你知道吗

Answer 1

return并不意味着它会重新开始。你的程序中没有任何东西会导致它重复。将其放入函数中，如果用户按“Y”，则再次调用该函数。你知道吗

while 1:
    print ("Input a binary number")

    num1 = int(input() , 2)

    print ("again please")

    num2 = int(input() , 2)

    answer = num1 + num2

    binaryanswer = bin(answer)[2:]

    print ("That's " ,binaryanswer, " In behhieerryy")

    again = input ("Press enter to end Program")          



    if again != 'Y':
        break

    print("AGAAAINN!!")
