elif和else命令被完全忽略，相反，无论我键入什么，即使是随机字母，我都会得到我的答案

Question

在我完成下面的代码后，我检查了它是否有效。问题是，无论我键入什么，它总是显示“如果”的响应，即使我更改了响应

我试着改变立场和反应，但没有任何效果

hello = input ("Hello there! \n My name is PIM. \n It `enter code here` stands for Primary Interactive Machine. \n What is your name?")
print ("Nice to meet you," + hello)
ans1 = input ("Can I ask you a question? <yes/no>")
if (ans1 == 'yes',' yes')                              
    ans2 = input ("Which color do you prefer? <blue/pink>")
elif(ans1 == 'no',' no'):
    print ("Well then, we will just stay in silence")
else:
    print ("I will not talk to someone who doesn't care about me. \n You had one simple job, choose yes or no and even then, you failed.")

预期它会相应地回复响应，但它只发送“if”回复

试试这个：

if ans1 in( 'yes' , ' yes'):                             
    ans2 = input ("Which color do you prefer? <blue/pink>")
elif ans1 in( 'no' or ' no'):
    print ("Well then, we will just stay in silence")
else:
    print ("I will not talk to someone who doesn't care about me. \n You had one simple job, choose yes or no and even then, you failed.")
