It's not a new instance of Python, but it is a new module, so it's a
separate namespace. When the script finishes, the variables from that
namespace are dumped in your interactive namespace, but that doesn't apply
to variables created in its module namespace later on (which is what you're
A simple workaround if you do want to see those variables is to use %run -i
x.py to run it directly in the main namespace.
