Dictionary keys match on list; get key/value pair

(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}

python list dictionary match key

Don't use dict and list as variable names. They shadow the built-in functions. Assuming list l and dictionary d:

kv = [(k, d[k]) for k in l if k in d]

python list dictionary match key

 new_dict = dict((k, v) for k, v in dict.iteritems() if k in list)

Turning list into a set set(list) may yield a noticeable speed increase
