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

You can use the following code:

keys = set(l1).intersection(set(d1.keys()))
result = {k:d1[k] for k in keys}

EDIT: As commenters suggest you can replace the first line with, in Python 2.x:

keys = set(l1).intersection(d1)

And in Python 3.x:

keys = d1.keys() & l1
