In the side note :

As one can see, tt's written in the side note «» and “” but should be of course " ' since we're talking about the real " and ' characters in the python language.

For fixing the bug, I've looked to :
https://github.com/python/python-docs-fr/blob/707f05d2d753fc3836c38b4f1ca0890da7628412/tutorial/introduction.po
And as one can see, the string are correctly written with " and ' so I guess it's the translation process that wrongly replaces to «» “”.
