VIM Regex for Matching Markdown Titles

I want to use regex to match markdown titles which start with 1-6 # marks, however, in the markdown file, there are python code snippets with comments start with #, which could be considered as markdown title wrongly.

Could you find a regex which can parse markdown title corrently? for example I have below markdown snippets:

# This is a title

## This is also a title

```python   
import os

# this is a comment, not a title  
os.system("pause")  
```

Another general way to do that is:

:%s/\(```python\_.\{-}```\)\|^\(\W\+\)\@<!/**\1

Then:

:%s/^\#\(.*\)/"\1"

Finally:

%s/^\**//g

Example, before:

# This is a title

## This is also a title

```python   
import os

# this is a comment, not a title  os.system("pause")  
```
# This is a title

## This is also a title

```python   
import os

# this is a comment, not a title  os.system("pause")

print("Blah blah")  

# this is another comment  
```

After:

# This is a title

## This is also a title

```python   
import os

" this is a comment, not a title  os.system("pause")  "
```
# This is a title

## This is also a title

```python   
import os

" this is a comment, not a title  os.system("pause")"

print("Blah blah")  

" this is another comment  "
```

Another simpler way is:

:%s/\(```\_.\{-}```\n\)\zs\|#\+\( .*\)/"\2 "/g

If I understand, this will help you:

:%s/^\(\(```python\(.*\n\(^```.*$\)\@!\)\+.*#\)\)/\1**/g

then:

:%s/\#\*\*\(.*$\)/"""\1"""/g

First one will change the # character inside every python snippet to #** at the snipped python code.

Last one will change #** to a more python general format """ comment """

LIMITATIONS: only works for only one comment by snippet.
