how to use loop & time with raw_input

Hi, I'm trying to run code that asks a yes or no question. If a yes or no isn't entered, then the question will continue to re-ask say every 3 seconds until a yes or no is entered. Here's the basics of it:

Python Syntax (Toggle Plain Text) 
  1. while True:
  2. response = raw_input(" Are you ready? ")
  3. if response.lower() == "yes":
  4.      print ("Then lets get started!")
  5.      break
  6. elif response.lower()=="no":
  7.     print ("Please try again later....")
  8.     break
  9. else:
  10.     print ("Please enter a 'yes' or 'no' response!")

With that, I can add another while True: after the last 'else' statement but that's not exactly what I'm after. Instead, I'd like the first question "Are you ready?" to keep repeating until 'yes' or 'no' is entered. Can I somehow incorporate sleep() in this and how can I get the raw_input question to keep repeating? Example output:

>>> Are you ready? maybe
>>>Are you ready?
(3 second delay, if no answer ask again)
>>>Are you ready?
(3 second delay, if no answer ask again)
>>>Are you ready?
(3 second delay, if no answer ask again)
>>>Are you ready?yes
"Then lets get started!"

Try:

Python Syntax (Toggle Plain Text) 
  1. import time
  2.  
  3. response=raw_input("Are you ready?\n")
  4.  
  5. while(response.lower()!="no"):
  6.     if(response.lower()!="yes"):
  7.         time.sleep(3)
  8.         response=raw_input("\nAre you ready?\n")
  9.     if(response.lower()=="yes"):
  10.        raw_input("Let's get started!")
  11.        break

Hope it works!

that wont work, the only problem is the while loop, what you actually want is:
python Syntax (Toggle Plain Text) 
  1. import time
  2.  
  3. response=raw_input("Are you ready?\n")
  4.  
  5. while (response.lower() != "yes"):
  6.   if (response.lower() = "no"):
  7.     time.sleep(3)
  8.     response=raw_input("\nAre you ready?\n")
  9. raw_input("let's get started!")
all i did was change the loop so that you didnt need to have the code for checking if it is yes and then it will simply break to carry on
don't judge me because I'm a year 8!

it works but not what kiddo asked for, the application that he/she wants, wants to check for keyboard inactivity and if 3 seconds passed it prints the question 'Are you ready yet' again.

kiddo might have to use a thread and a hook to the keyboard to get tis to go
