Slicing a dictionary

Question

I have a dictionary, and would like to pass a part of it to a function, that part being given by a list (or tuple) of keys. Like so:

# the dictionary
d = {1:         


        

Answer 1

set intersection and dict comprehension can be used here

# the dictionary
d = {1:2, 3:4, 5:6, 7:8}

# the subset of keys I'm interested in
l = (1,5)

>>>{key:d[key] for key in set(l) & set(d)}
{1: 2, 5: 6}
