Actually thinking a bit and researching a little more this is wrong: https://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals Looking in to the Python Language reference I see that it is possible to use mix two: stringprefix ::= "r" | "u" | "R" | "U" | "f" | "F" | "fr" | "Fr" | "fR" | "FR" | "rf" | "rF" | "Rf" | "RF" The issue that confused me is that since we need to keep the compatibility with python2 we need to use the u prefix. The u prefix was supported in Python 3 just version 3.3. Previously it was available in python2: "New in version 3.3: Support for the unicode legacy literal (u'value') was reintroduced to simplify the maintenance of dual Python 2.x and 3.x codebases. See PEP 414 for more information." So actually the code above could simply be used as fr"\begin_layout {layout}" this only works for Python 3.6+, when the formatted strings were introduced. Apologies for this series of Python musings. :-D -- José Abílio -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel
