名称错误：名称'；宠物&x27；没有定义。python

这是我正在使用的代码，但每次我尝试运行它时，终端中都会出现以下错误：

Traceback (most recent call last):
  File "ex11.py", line 16, in <module>
    if pets == "y":
NameError: name 'pets' is not defined

您的问题是，如果

“Good”

不在

emotion

中，

pets

不会被定义。因此，首先定义它：

print "So, how are you doing today?"
emotion = raw_input()
pets = "n" #here

if "Good" in emotion:
    print "Cool! I love when people are \"good\"! It makes me feel all fuzzy inside. ^-^"
    print "Do you have any pets? y/n."
    pets = raw_input()

if pets == "y":
    print "Awesome! I have always wanted a pet! What kind do you have? What does it look like?"
    pet_type = raw_input()
