title: if True and if False statements
body: <p>I've always been confused about using True and False on if statements. For instance, let's say that I've defined a function that returns True or False.</p>
  
  <pre><code>def isEven(number):
      if number % 2 == 0:
          return True
      else:
          return False
  </code></pre>
  
  <p>Now I need to use that function on one of my code which can only proceed if the number is even. I believe I have seen codes like <code>if isEven(number): proceed etc etc</code>, my question is, is it considered True by default? Or should I keep using <code>if isEven(number) == True</code></p>
