Thanks for the guidance - it was indeed an issue with reading in binary vs. text., and I do now succeed in reading the last line, except that I now seem unable to split it, as I demonstrate below. Here's what I get when I read the last line in text mode using 2.7.1 and in binary mode using 3.2 respectively under IDLE:
2.7.1 Name 31/12/2009 0 0 0 3.2 b'Name\t31/12/2009\t0\t0\t0\r\n' if, under 2.7.1 I read the file in text mode and write >>> x = lastLine(fn) I can then cleanly split the line to get its contents >>> x.split('\t') ['Name', '31/12/2009', '0', '0', '0\n'] but under 3.2, with its binary read, I get >>> x.split('\t') Traceback (most recent call last): File "<pyshell#26>", line 1, in <module> x.split('\t') TypeError: Type str doesn't support the buffer API If I remove the '\t', the split now works and I get a list of bytes literals >>> x.split() [b'Name', b'31/12/2009', b'0', b'0', b'0'] Looking through the docs did not clarify my understanding of the issue. Why can I not split on '\t' when reading in binary mode? Sincerely Thomas Philips -- http://mail.python.org/mailman/listinfo/python-list
