Reasons are:
- The prompt says 2.7.3 Sep 26 2013, which makes the tutorial look
outdated
- There is another section that explains how snippets should be
executed in a Python interactive interpreter
- The only activity in the snippet is importing tuf functions and
creating a repo, both of which is done in another snippet below.
And the here created repo is not re-used
- The tutorial is long enough
