Dictionary keys match on list; get key/value pair

Question

In python... I have a list of elements \'my_list\', and a dictionary \'my_dict\' where some keys match in \'my_list\'.

I would like to search the dictionary and retrieve

Answer 1

(I renamed list to my_list and dict to my_dict to avoid the conflict with the type names.)

For better performance, you should iterate over the list and check for membership in the dictionary:

for k in my_list:
    if k in my_dict:
        print k, my_dict[k]

If you want to create a new dictionary from these key-value pairs, use

new_dict = {k: my_dict[k] for k in my_list if k in my_dict}
