Say your string is s; then you could use the following 
function (untested!) to make sure that s uses \n only: 

    def fix_lineendings(txt):
        if txt.count('\r\n'):  # MS DOS
            txt = txt.replace('\r\n', '\n')
        elif txt.count('\r'):  # Mac
            txt = txt.replace('\r', '\n')
        
        return txt

Simply write: s = fix_lineendings(s)
