is the last line of your file empty ??
what with

That doesn't work. I just get an error:
x = eval(line.strip('\n'))
File "", line 1

SyntaxError: unexpected EOF while parsing
any other ideas?

Hi,
I have a text file called a.txt:

I read it using this:

If you are using 2.4 or later, you can simply use "set" without
importing anything.

memory failing me, or have I seen such an Python-example somewhere? I
