Ah ok, thanks! That worked, though the line "str1, str2, blank, height, width, num2, num3 =" spit out a syntax error. However, I do see that it creates a tuple with all the values in a readable format for me. Also, I needed to change info.read(15) to 16. More questions: What is this value for? "6s3s1cBBBh" and why is my unpack limited to a length of "16"? Unfortunately it seems my understanding of binary is way too basic for what I'm dealing with. Can you point me to a simple guide to explaining most of it? As far as I know this is just a bunch of 1's and 0's right? Each byte has 8 digits of, of which somehow is converted to a number or letter. Don't know what most of that stuff in the struct page means. -_- As for you questions, I suppose it would be "little-endian" as the format is on PC (and the Python docs say: "Intel and DEC processors are little-endian"). 0-5 means a single digit "0" through "5". Lastly, I'm not building the format, it's already made (a format for tiled maps in a game). My program is just reading it. -- http://mail.python.org/mailman/listinfo/python-list
