With reference to another reply here, the "Weird stuff" came from
reading the question, finding it unclear, and only later realising that
whereas most people write Markdown-formatted documents for later
processing, or perhaps docstrings in Markdown-format for collection by documentation systems; here, the objective appears to be using Python to generate Markdown.
How much have you used Markdown to any serious degree, before attempting
this feat?

The web claims (I think on all pages I've read about Markdown and Python) that this code should work, with some very minor variants on the topic:
There are so many "variants", the problem is not "minor"!
Markdown users learn to use their tool (again, see @Grant's question)
and work within the implementation of that "variant".
Like any other non-standardised tool, the users of some particular
'version' often fail to realise that others using different versions may
not enjoy the same experience. Plus-one for standardisation!
At the end of the message, the web.refs reveal use of a package which is
based upon a variant of Markdown that is 20-years old(!), albeit with
some updates to suit yet another variant. Neither variant-author famous
for collaboration. The phrase YMMV springs to mind...
Some ten years ago, an effort was made to standardise Markup, and it
ended-up being called CommonMark. Why is it not called "Standard
Markdown" one might ask? Because the fellow who 'invented' Markdown
objected. This very objection has likely led directly to your
confusions, because the particular PyPi package is based upon that
original definition...
Whereas, Markdown 3.6 is the most-recently updated Markdown search-hit
on PyPi today, have you tried any of the others (which, ironically, may
offer more recent and/or more standardised coverage)?
This has worked in all of the Markdown processors I have used or tried-out:
The (?reasonable) 'common-core', offers single back-ticks for code,
triple back-ticks for a code-block, and the latter with or without a
language specification which *usually* kicks-in syntax highlighting.
```python
import os
with open(os.path.join('/home/user/apath', 'somefile')) as f:
print(f.read())
```
However, that is not the case. At least not for me (using Python 3.12.3).
It's not Python 3 that is the problem. It is the "Markdown 3.6" package!
If instead I type it:
I've not seen the hash-bang combination in-the-wild (but YMMV!)
#!python
import os
with open(os.path.join('/home/user/apath', 'somefile')) as f:
print(f.read())
As an indented block (four spaces) and a shebang, THEN it works. You even
get line numbers by default.
An indented-block is NOT necessarily the same as a code-block - just as
"code" is not necessarily "Python".
Line numbers are great - although if a code snippet is extracted from
the middle of some example code-file, the original line-numbers won't
line-up with Markdown's...
N.b. if you don't know, you also need to generate a css file using
pygments to make this work.
That's not what the package's docs suggest:
https://python-markdown.github.io/extensions/fenced_code_blocks/
Not until I started to read the markdown source code and its docs pages,
the coin dropped.
I'm posting this for other Markdown newbies that otherwise probably would spend hours trying to make it work.
Speaking of Markdown. Does anybody out there have any idea how to turn on table borders, adjust them (color/width/etc.) and such things? Currently I have to add HTML to do so, which works, but isn't very nice. I'd hate to spend an additional day or two, hunting for this info.
Again, heavily dependent upon the tool in-use. For example, most SSGs
and doc-tools (which accept Markdown) have a .css or theming-system
which enables 'decorations'.
