title: Python-passing variable between classes
body: <p>I'm trying to create a character generation wizard for a game. In one class I calculate the attributes of the character. In a different class, I'm displaying to the user which specialties are available based on the attributes of the character. However, I can't remember how to pass variables between different classes.</p>
  
  <p>Here is an example of what I have:</p>
  
  <pre><code>class BasicInfoPage(wx.wizard.WizardPageSimple):            
      def __init__(self, parent, title):
           wiz.WizardPageSimple.__init__(self, parent)
           self.next = self.prev = None
           self.sizer = makePageTitle(self, title)
  
                      &lt;---snip---&gt;
  
           self.intelligence = self.genAttribs()
  
  class MOS(wx.wizard.WizardPageSimple):
       def __init__(self, parent, title):
           wiz.WizardPageSimple.__init__(self, parent)
           self.next = self.prev = None
           self.sizer = makePageTitle(self, title)
        def eligibleMOS(self, event):
            if self.intelligence &gt;= 12: 
                 self.MOS_list.append("Analyst")
  </code></pre>
  
  <p>The problem is that I can't figure out how to use the "intelligence" variable from the BasicInfoPage class to the MOS class. I've tried several different things from around the Internet but nothing seems to work. What am I missing?</p>
  
  <p><strong>Edit</strong> I realized after I posted this that I didn't explain it that well. I'm trying to create a computer version of the Twilight 2000 RPG from the 1980s.</p>
  
  <p>I'm using wxPython to create a wizard; the parent class of my classes is the Wizard from wxPython. That wizard will walk a user through the creation of a character, so the Basic Information page (class BasicInfoPage) lets the user give the character's name and "roll" for the character's attributes. That's where the "self.intelligence" comes from.</p>
  
  <p>I'm trying to use the attributes created her for a page further on in the wizard, where the user selects the speciality of the character. The specialities that are available depend on the attributes the character has, e.g. if the intelligence is high enough, the character can be an Intel Anaylst.</p>
  
  <p>It's been several years since I've programmed, especially with OOP ideas. That's why I'm confused on how to create what's essentially a global variable with classes and methods. </p>
