Find dictionary items whose key matches a substring

Question

I have a large dictionary constructed like so:

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


        

Answer 1

An iteritems and a generator expression will do this:

d={'New York':'some values',
    'Port Authority of New York':'some more values',
    'New York City':'lots more values'}

print list(v for k,v in d.iteritems() if 'new york' in k.lower())    

Output:

['lots more values', 'some more values', 'some values']
