title: Call Class Method From Another Class
body: <p>Is there a way to call the method of a class from another class? I am looking for something like PHP's <code>call_user_func_array()</code>.
  Here is what I want to happen:</p>
  <pre><code>class A:
      def method1(arg1, arg2):
          ...
  
  class B:
      A.method1(1, 2)
  </code></pre>
