python-markdown无法识别代码块？

Question

我在一个脚本的工作转移Markdown到HTML,我都试过markdown和markdown2.当我用MathJax它来使它能够在LaTex中显示数学公式时,我发现markdown对我来说比对我更好markdown2.但是,它们都无法识别代码块```.我的代码写的是Python.

我的Markdown代码是:

?????????

```

from math import log

def calcShannonEnt(dataSet):
   numEntries = len(dataSet) #????
   labelCount = {}
   for featVec in dataSet: #??????
       currentLabel = featVec[-1] #currentLabel????????
       if currentLabel not in labelCount.keys(): #??
           labelCount[currentLabel] = 0
       labelCount[currentLabel] += 1
   shannonEnt = 0.0
   for key in labelCount.keys():
       prob = float(labelCount[key]) / float(numEntries)
       shannonEnt -= prob * float(log(prob,2))#?????
   return shannonEnt

```

我希望那些汉字不要打扰你.HTML代码是:

<p>?????????</p>
<pre><code>```

from math import log

def calcShannonEnt(dataSet):
   numEntries = len(dataSet) #????
   labelCount = {}
   for featVec in dataSet: #??????
       currentLabel = featVec[-1] #currentLabel????????
       if currentLabel not in labelCount.keys(): #??
           labelCount[currentLabel] = 0
       labelCount[currentLabel] += 1
   shannonEnt = 0.0
   for key in labelCount.keys():
       prob = float(labelCount[key]) / float(numEntries)
       shannonEnt -= prob * float(log(prob,2))#?????
   return shannonEnt

```

有什么问题？

在@Waylan 的帮助下，问题已经完美解决。那是因为我没有启用扩展。查看扩展

现在是对的：

html_txt = markdown.markdown(post.body_markdown, extensions=['fenced_code'])
