Python - intersection between a list and keys of a dictionary

Question

I have a list that looks like this:

l1 = [\'200:200\', \'90:728\']

I have a dictionary that looks like this:

d1 = {\'200:20         


        

Answer 1

Not sure about each solution performance, but I would do:

{k: v for k, v in d1.items() if k in l1}
