title: Python: function, passing argument
body: <p>I`m new to python and I have the stupid problem with passing an argument.</p>
  
  <pre><code>class MyClass():
  
      @staticmethod
      def add_group(name, parent_id):
          print "add_group method, name: %s, parent_id: %s" % (name, parent_id)
  </code></pre>
  
  <p>Other class method</p>
  
  <pre><code>def task():
      print "task method, name: %s, group_id: %s" % (name, parent_id)
      MyClass.add_group(name, parent_id)
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>task method, name: blabla, group_id: 15
  
  add_group method, name: blabla, parent_id: (15L,)
  </code></pre>
  
  <p>What's happened with parent_id argument? Any help would be appreciated!</p>
