markup problem with embedded python

[cfhowes]

If you put 2 python code segments on a page too close to each other the second one will not get pulled out of the page text and will be interpreted by markdown.

for example:
"""
Hello World

{{=plugin_comments('t_page',page.id)}}
text
{{=plugin_rating('t_page',page.id)}}
sometext
{{=page.id}}
other stuff
"""

will have the "plugin_rating" section skipped, and markdown will convert it to "pluging<em>rating" and the layout will fail.

a potential fix that works so far for me is:
