How to compare list values with dictionary keys and make a new dictionary of it using python

Question

I have a list like this:

lis = [\'Date\', \'Product\', \'Price\']

I want to compare it with:

dict = {\'Date\' : \'2013-05-0         


        

Answer 1

filtered_dict = dict((k, original_dict[k]) for k in lis if k in original_dict)

Or if you have 2.7+:

filtered_dict = {k: original_dict[k] for k in lis if k in original_dict}

If you want to use a generator:

item_generator = ((k, original_dict[k]) for k in lis if k in original_dict)

The generator will yield (key, value) pairs.
