switch key and values in a dict of lists

Question

Hello Stackoverflow people,

I have a nested dictionary with lists as values and I want to create a dict where all the list entries get their corresponding key as value.<

Answer 1

assuming your key: value dictionary contains list as a value and using dict comprehension.

Using a second loop to iterate over the list present in original dictionary.

{item: key for key, value in dict1.items() for item in value}
