Question

im trying to download python for the course (introduction to computer science and programming) v2.5.4 however when i try to do the strings in the second lecture it does not provide the same outcome, ex: type (none), it gives me
IDLE 1.2.4
>>> type (none)

Traceback (most recent call last):
File "", line 1, in type (none) NameError: name 'none' is not defined >>> anyone knows where to find the right version or what to do in the current version that i have

Answer 1

none or None?

https://docs.python.org/2/library/constants.html

Answer 2

none
if you have seen the lecture, the outcome is different

Answer 3

You did not get the point. Even in 2.5.4 it was None, not none. Here are the docs:
https://docs.python.org/release/2.5.4/lib/node8.html

Answer 4

Here it is in 2.7.6:

```
Python 2.7.6 (default, Nov 10 2013, 19:24:24) [MSC v.1500 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> type(none)

Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
type(none)
NameError: name 'none' is not defined
>>> type(None)
<type 'NoneType'>
>>>
```
But the results should be the same in basically any version.
