    return {thing: 1 for thing in nums1 if thing in nums2}.keys()
    

    Use a dictionary comprehension with a conditional to get all keys in both lists. The dictionary will make sure that the keys are unique; then, just return the keys from the dictionary.

    Or, using sets.

    return list(set(nums1).intersection(nums2))
