Extension for Python-Markdown to handle <figure> and <figcaption>.

• %%% start a <figure>
• %: start a <figcaption>

from markdown import Markdown
text = r'''
%%%

%%% figure-class here
    ![img-alt](/source/of/img.jpg){: img-attributes here}

    %: figcaption here
    {: figcaption-attributes here}

%: will not be a figcaption
'''
md = Markdown(extensions=['markdown_figcap','attr_list'])
print(md.convert(text))

Output:

<p>%%%</p>
<figure class="figure-class here">
<img alt="img-alt" here="here" img-attributes="img-attributes" src="/source/of/img.jpg" />
<figcaption figcaption-attributes="figcaption-attributes" here="here">figcaption here</figcaption>
</figure>
<p>%: will not be a figcaption</p>

• The attributes rendering (except <figure>'s class) is supported by the origin Python-Markdown's attr_list extension.
• Figure starter only will not be rendered as <figure>.
• Figcaption starter will not take effect until it is in the figure block.
• If the <p> in <figure> has no text and only one <img> child, the <p> tag will be got rid of.

From PyPI:

pip install markdown-figcap
