If statement checking for certain text in rawinput never changes

In the code below, the problem seems to be on line 16. What happens is that when I run the code, no errors occur, but when I want to type something, for some reason the only thing that the code says is "What is your name?", which is not supposed to happen. What I think the problem is is that the hi and the hello and all that is somehow being read in my input, even when I input a space and nothing else. What am I doing wrong and what do I have to do to fix it? Thanks!
