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?
