Swap key and value of a dictionary - and sort it

[Omid]

Hello,

The input is this:

Output:
{'Accurate': ['exact', 'precise'], 'exact': ['precise'], 'astute': ['Smart', 'clever'], 'smart': ['clever', 'bright', 'talented']}

And the output is supposed to be this:

Output:
{'precise': ['accurate', 'exact'], 'clever': ['astute', 'smart'], 'talented': ['smart'], 'bright': ['smart'], 'exact': ['accurate'], 'smart': ['astute']}

Note that values of each key are sorted.

My code is this:

def reverse_dictionary(input_dict):

    my_dict= {}

    for key, value in input_dict.items():
        for string in value:
            my_dict.setdefault(string.lower(), []).append(key.lower())
    
    output_dict={k:v for k,v in sorted(my_dict.items(), key=lambda item:item[1])}

    return output_dict

But this code is not producing the expected result. What am I missing here?
