How can I write a function that does nothing for a given length of time?

Question

Here's what I tried (Python):

import time

def wait(seconds):
    start_time = time.time()
    while start_time + seconds <= time.time():
        pass

But this just quits instantly.

Answer 1

The following code will efficiently sleep for a specified amount of time

import time
time.sleep(1) # delays for 1 second
