How to convert java regex pattern into python re pattern?

private static final Pattern pattern = Pattern.compile(
        "(\\d+)(,)?" +                 
        ".{4},?" +                     
        "\\d*" +                       
        "(\\d{2})(\\d{2})(\\d{2}),?" + 
        "([AV]),?" +                   
        "(\\d{2})(\\d{2}\\.\\d+)" +    
        "([NS]),?" +
        "(\\d{3})(\\d{2}\\.\\d+)" +    
        "([EW]),?" +
        "(\\d+\\.\\d)(?:\\d*,)?" +     
        "(\\d{2})(\\d{2})(\\d{2}),?" + 
        "(\\d+\\.?\\d+),?" +           
        "([0-9a-fA-F]{8})?,?" +        
        "(?:L([0-9a-fA-F]+))?\\)?");   

I am trying to convert the above java pattern into python but failed to do.
