title: Declaring a Variable in Python without giving a value
body: <pre><code>print ("please enter a number : ")
  Num1= None
  Num2= None
  sum = 0
  input (Num1)
  print(Num1)
  </code></pre>
  
  <p>I tried the above code and although the code works it gave me the result:</p>
  
  <p>Please Enter A Number:
  None</p>
  
  <p>I do not want the "None" in the output.</p>
  
  <p>Is there a way to fix this problem?</p>
