I would like to check to see if the data files are good, readable, and exist. I have checked to see if they exist, but their is a possibility that the data file might be binary, and I would like to have a sys.exit for that as well.
if not os.path.isfile(A_data) or not os.path.isfile(B_data)\ or not os.path.isfile(C_data) or not os.path.isfile(D_data): sys.exit(14) -- "The game of science can accurately be described as a never-ending insult to human intelligence." - João Magueijo
