我的 Python if else 语句有什么问题？

Question

PersonsName = input('Enter your name: ')
print('Hello', PersonsName)

AnswerToHowAreYouToday = input('How are you feeling today? Are you doing Good or Bad?')


print('Ok', PersonsName,'So today you are basically feeling', AnswerToHowAreYouToday, '.')


a = "Good"
b = "Bad"
if AnswerToHowAreYouToday: a
print('Good')
else:
    print('Bad')

Answer 1

您的 if else 语句缩进是错误的。 通常四个空格用于缩进，比制表符更受欢迎。 在行继续中可以忽略缩进。 但总是缩进是个好主意。

PersonsName = input('Enter your name: ')
print('Hello', PersonsName)

AnswerToHowAreYouToday = input('How are you feeling today? Are you doing Good or Bad?')


print('Ok', PersonsName,'So today you are basically feeling', AnswerToHowAreYouToday, '.')


a = "Good"
b = "Bad"
if AnswerToHowAreYouToday == a:
    print('Good')
else:
    print('Bad')

Answer 2

你的if AnswerToHowAreYouToday: a应该是这样if AnswerToHowAreYouToday == a 。 @Santhos 已经提到它但是当你的代码运行你的输出显示时

Enter your name: Deepak                                                                                                              
Hello Deepak                                                                                                                         
How are you feeling today? Are you doing Good or Bad?Good                                                                            
Ok Deepak So today you are basically feeling Good .                                                                                  
Good 

您可以看到最后打印了两个 Good 。 为了避免这些问题，您可以像这样改进代码

PersonsName = input('Enter your name: ')
print('Hello', PersonsName)

AnswerToHowAreYouToday = input('How are you feeling today? Are you doing Good or Bad? ')

print('Ok', PersonsName,'So today you are basically feeling ', end = '')

a = "Good"
b = "Bad"
if AnswerToHowAreYouToday == a:
    print('Good.')
else:
    print('Bad.')

然后输出将是：

Enter your name: Deepak                                                                                                              
Hello Deepak                                                                                                                         
How are you feeling today? Are you doing Good or Bad? Good                                                                            
Ok Deepak So today you are basically feeling Good.
