title: How to set a bias on multiple methods within a class?
body: <p>Disclaimer: Python newb</p>
  
  <p>My code</p>
  
  <pre><code>class summation():
  
      def __init__(self, num_1, num_2):
  
          self.add_1 = num_1 + num_2
          self.multiply = num_1 * num_2
          self.divide = num_1 / num_2
          self.difference = num_1 - num_2 
  
      def summate(self):
          return '{}'.format(self.add_1)
  
      def mult(self):
          return '{}'.format(self.multiply)
  
      def divis(self):
          return '{}'.format(self.divide)
  
      def diff(self):
          return '{}'.format(self.difference)
  
  input_values = summation(int(input()), int(input()))
  
  print('Sum =', input_values.add_1)
  print('Multiplied =', input_values.multiply)
  print('Divided =', input_values.divide)
  print('The difference between the two values is ',input_values.difference)```
  
  </code></pre>
  
  <p>I want to include a bias method which will take the values input by the user and apply a bias on them that can be easily changed</p>
  
  <p>I.E. user inputs (2) and (3) and the bias applies a 1.02 multiplier on them</p>
  
  <p>so something that starts like this</p>
  
  <pre><code>bias = 1.04
  
  def apply_bias(self):
          return input_values * bias
  </code></pre>
  
  <p>Obviously this doesn't work but it gives you an idea</p>
  
  <p>Anyone have any ideas?
  Cheers</p>
