title: TypeError: 'bool' object is not callable python
body: <p>whenever I try run this code, I receive a TypeError: 'bool' object is not callable.
  How could I fix this code to make it so that when I try and print bike.blue() I get a boolean value?</p>
  <pre><code>class Colour():
      def __init__(self):
          self.blue = False
  
      def blue(self) -&gt; bool:
          return self.blue
  
  bike = Colour()
  print(bike.blue())
  </code></pre>
