「好天」的劇本

Question

我剛開始使用Python，我似乎無法得到這個腳本工作：

name = input('Enter your name in quotes: ') 
print 'Hello,' + name +'!' 
age = input('Please enter your age with no quotes: ') 
print 'Hi again, ' + name +'! I see you are' ,age, 'years old.' 
color = input('What is your favorite color, in quotes? ') 
print 'I like the color ' + color + ' too, ' + name + '!' 
good_day = input('Are you having a good day? Type "Yes" or "No" ') 
if good_day == Yes : 
    print 'That is good, ' + name + '!' 
else : 
    print 'I hope your day gets better, ' + name + '!' 

它正常工作，直到你回答這行：

good_day = input('Are you having a good day? Type "Yes" or "No" ') 

在此之後，它說：

Traceback (most recent call last): 
    File "/Users/mtreadwell/Desktop/getage.py", line 8, in <module> 
    if good_day == Yes : 
NameError: name 'Yes' is not defined 

請幫助解決這個錯誤！

Answer 1

if good_day == Yes : 

Yes是你的問題。它應該是字符串，"Yes"。
