Question

这里有什么问题？在输入3（＆lt; = 5）时，输出应该是，我认为，“Phew，...”但它仍然是“很棒，......”

weather = raw_input('How is the weather today, from 0 to 10? ')
answer = raw_input ('Are you in mood to go out? ')
if weather >= 5:
    if answer == 'Yes':
        print 'Awesome, I will go out!'
        print 'Will you come with me?'
    else:
        print 'Awesome, I am going out now!'
elif weather <= 5:
    print "Phew, I didn't want to go outside, great, I will stay in! Thank God!"
else:
    print "Huh?"

Answer 1

raw_input返回的字符串不是整数，例如'3'代替3。

在Python 2中，字符串总是比大于整数，因此weather >= 5始终为真。

要解决此问题，请将weather转换为整数：

weather = int(raw_input('How is the weather today, from 0 to 10? '))

Answer 2

raw_input返回一个字符串，您需要将其转换为整数。

weather = int(raw_input('How is the weather today, from 0 to 10? '))

您需要捕获处理错误输入的任何异常。

elif块没有在Python中执行
