I have a large dictionary constructed like so:

programs['New York'] = 'some values...' 
programs['Port Authority of New York'] = 'some values...' 
programs['New York City'] = 'some values...'
...

How can I return all elements of programs whose key mentions "new york" (case insensitive)? In the example above, I would want to get all the three items.

EDIT: The dictionary is quite large and expected to get larger over time.

[value for key, value in programs.items() if 'new york' in key.lower()]
