Hi,
I have Python embedded with my other code, and when my other code opens
a console and redirects stdout, stdin and stderr to it, then calls

Hi,
I have a list that contains nodes from a tree. Each node is a class
instance, but I'll use dictionary here to simplify the example.
So the list looks like this:

'name': 'Parent node',
'ord_number': 1,
'parent_id': 0,
'url': '/parentnode/'},
{'id': 2,
'name': 'My node',

Hi there,
I'm pretty new to Python and am trying to figure out how to get "will
this code compile?"-like code checking. To me this is a pretty basic

In Python, functions can hold state in various ways: closures,
generators, and - Python functions being instances of the function class
