Python replace baffling me.

Ok so here it goes. 

def __init__(self, ids, usr, pwd, dsc) :  
        self.id = ids                                   
        print self.id + "hello"                   
        if " " in self.id :                             
            print "Ok has spaces"             
            print type(self.id)                   
            self.id.replace(" ", "_")         
            print self.id

Ok So I get 4 variables I create self.id. I print the id with the word hello next to it. Then I do an if statement. If the variable has white spaces, cool print ok it has spaces. Then I find out what type it is. Just to make double sure its a string. I then do a replace on the white spaces with _ and print the variable again. 

OUTPUT
wer eeq hello 
Ok has spaces
<type 'str'>
wer eeq         <<< -------WTF?

I print it, you can see yes it has a white space. The if method sees that and prints Ok has spaces. I double check it's a string which it is Then I do the replace print again but no _??? I have been staring at this and can't figure it out. It works in the interpreter, I tried re.sub nothing will change this string. Which makes me wonder if it's actually a string even though it says it is. There are no errors or anything.

So I am hoping you guys can help me out!

OHHHH BOOYYY!!! Sitting at the computer to long, went and got a beer and then DUH! lol

So if I do this

name = "John Doe"
name.replace(" ", "_")

In the interpreter the immediate response back is John_Doe. BUT, after lookin at the code for replace. It returns a variable. BUT I am not storing the variable that it's returning in anything. So I did this instead and it worked like a charm.

def __init__(self, ids, usr, pwd, dsc) :  
        self.id = ids                                                    
        if " " in self.id :                                                        
           self.id =  self.id.replace(" ", "_")         
            print self.id

Now when I pickle my stuff to a file, I can read it back from the file a lot lot better, considering I don't need to watch for spaces. And since the passwords and all the data is encrypted. It's not like you can read the file anyway. Ahhh dang. Finally past this this.
