Jupytext failed to recognise py file where md text ends up with '''

[pytkr]

Hi, I find .py file can be recognised and automatically generate corresponding .ipynb and .md files using jupyter notebook with Jupytext, but I cannot successfully make following Code 4 md cell correctly recognised as a md cell, and it just ruined the following cells into one cell where filled with {{{ and }}}:

Code 1 (OK): this will show normally as 1 code cell

# abcd
print('hello world')

Code 2 (OK): this will be recognised as 1 md cell and 1 code cell

# abcd

print('hello world')

Another syntex with the same effect

# {{{ {"cell_type": "markdown"}
# abcd
# }}}
print('hello world')

Or

# {{{ {"cell_type": "markdown"}
# abcd
# }}}

print('hello world')

Code 3 (OK): this will be recognised as 1 md cell and 1 code cell

# abcd'''

print('hello world')

Code 4 (Failed): this will be recognised as 1 cell, just like abcd''' }}} print('hello world')

{{{ {"cell_type": "markdown"}

abcd'''

}}}

print('hello world')

I don't know whether this a md issue or jupytext one, and hope this can be fixed.
Thanks!

Hello @pytkr , thanks for the detailed report! Sure we'll have to fix that.

I think that what happens is that the detection of strings (in stringparser.py) is not aware of the single line comment (# for Python). I am currently not in a position to propose a fix for this, but I will certainly have a look at this in early September.
