I can look at it. Would everyone be satisfied with a solution using regular expressions ? That is, looking for the following pattern: pattern = re.compile(r ^\s* # leading white space (.*) # Data %s? # Zero or one comment character (.*) # Comments \s*$ # Trailing white space

Hi Christopher, The advantage of using regular expressions is that in this case it gives you some flexibility that wasn't there before. For instance, if for any reason there are two type of characters that coexist in the file to mark comments, using pattern = re.compile(comments) for i,line in

Well, after all that said, I'm also fine with either approach. Anyway, I would say that my personal preference is for the one using 'str.index', as it is the simplest one regarding the old code. Like Christopher, I rarelly (never?) use 'loadtxt'. But this issue made a coworker to get crazy (he is
