python入门第五课

落梦

代码如下：
num= 123.456
print (num)
num=("hello")
print("who do you think l am ?")
you= eval(input())
you= ("oh yes! l am a")
print (you)

分割线----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
运行结果：
123.456
who do you think l am ?
"nice guy"
oh yes! l am a

问：为什么程序没有回答“oh yes l am a nice guy”

crossin先生

you= ("oh yes! l am a")
应该是
print("oh yes! l am a")
