Lastly, check the line or lines before the line highlighted. While python lists can contain values corresponding to different data types, arrays in python can only contain values corresponding to same data type. This analysis is limited to line, page, and column breaks. This parser also handles games without any headers just fine. Is this possible? Thanks in advance.
