Answer: 
Check if there's no your own version of `io.py` using following command.

```
C:\> python -c "import io; print io.__file__"
c:\python27\lib\io.pyc

```

You should see similar output.

If there's your own version, it shadows builtin version of `io` package. Rename your own module with a name that does not collide with standard module. (Don't forget `pyc` files.)
in my case.
