title: Error in Time Sleep
body: <p>There is an error in this code...</p>
  
  <pre><code>time.sleep(5)
  print ("Loading Successfull")`
  </code></pre>
  
  <p>When I run this code an error pops up it says:</p>
  
  <pre><code>NameError: name 'time' is not defined
  </code></pre>
  
  <p>I think I dont need to define time </p>
  
  <p>I've recently have used this command it never said <code>TimeError</code> it's happening first time</p>
  
  <pre><code>print ("-----------------Welcome to Digits counter-----------------")#Welcomes the user
  print ("")
  print ("Loading...")
  time.sleep (3)
  print("Load Sucessfull")
  </code></pre>
