title: Can I deploy a common function when using Google Cloud Function by Python?
body: <p>I have created a Common class that will be used in common and am approaching from the A function and B function.</p>
  
  <p>If I add variables to the Common class, you must deploy both A and B classes.</p>
  
  <p>How can I apply the Common class take effect without deploy all the A and B functions?</p>
  
  <pre><code>class Common:
      def __init__(self, tmp):
          self.FIRST = tmp
          self.SECOND = 'Test' # new.
  
      # I want to modify this function.
      # but I have to deploy function A and B.
      # If I have a lot of functions I need a lot of time.
      def print_value(self):
          print(self.FIRST) # old.
          print(self.FIRST, self.SECOND) # new.
  
  class A:
      def __init__(self):
          o = Common('A')
          o.print_value()
  
  class B:
      def __init__(self):
          o = Common('B')
          o.print_value()
  </code></pre>
