Update a dict values with values in a list

Question

I have a dictionary I want to update:

my_dict = {"a":"A", "b":"B"}

and a list with the exact same length:

my_list = ["D", "E"]

I would like to find the most efficient way to update my_dict with the values from my_list to:

{"a":"D", "b":"E"}

without having to run multiple for loops or similar. I tried to do this with list comprehensions, but it does not allow multiple statements:

{my_dict_key:list_item for my_dict_key in my_dict.keys(), list_item in my_list}

Answer 1

Use zip() with a dictionary-comprehension:

{key: value for key, value in zip(my_dict, my_list)}

Or just:

dict(zip(my_dict, my_list))
