python fenced code blocks

Python version: Python 2.7.3
markdown2 version: 2.1.0
SO: windows

In python code methods inside clases are considerated "< pre > < code >..."

Example:

class BezierDrawer(QtGui.QWidget):
    """Draw a Bezier Curve"""
    def __init__(self):
        super(BezierDrawer, self).__init__()
        self.setGeometry(300, 300, 450, 450)
        self.setWindowTitle("Bezier Curves")

    def paintEvent(self, e):
        qp = QtGui.QPainter()
        qp.begin(self)
        qp.setRenderHints(QtGui.QPainter.Antialiasing, True)
        self.doDrawing(qp)        
        qp.end()

Result:

<span class="k">class</span> <span class="nc">BezierDrawer</span><span class="p">(</span><span class="n">QtGui</span><span class="o">.</span><span class="n">QWidget</span><span class="p">):</span>
    <span class="sd">&quot;&quot;&quot;Draw a Bezier Curve&quot;&quot;&quot;</span>
    <span class="k">def</span> <span class="nf">__init__</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span>
        <span class="nb">super</span><span class="p">(</span><span class="n">BezierDrawer</span><span class="p">,</span> <span class="bp">self</span><span class="p">)</span><span class="o">.</span><span class="n">__init__</span><span class="p">()</span>
        <span class="bp">self</span><span class="o">.</span><span class="n">setGeometry</span><span class="p">(</span><span class="mi">300</span><span class="p">,</span> <span class="mi">300</span><span class="p">,</span> <span class="mi">450</span><span class="p">,</span> <span class="mi">450</span><span class="p">)</span>
        <span class="bp">self</span><span class="o">.</span><span class="n">setWindowTitle</span><span class="p">(</span><span class="s">&quot;Bezier Curves&quot;</span><span class="p">)</span>
