my_dict = dict()
my_list = ["aaa", "bbb"]
for el in my_list:
    my_dict[el] = []

print (my_dict)

output:

{'aaa': [], 'bbb': []}

or use list comprehension:

my_dict = dict()
my_list = ["aaa", "bbb"]

print ({el:[] for el in my_list})

output:

{'aaa': [], 'bbb': []}

If my_dict is already existing dict and you want to add more items to that then you can use the below code

my_dict.update({key:[] for key in my_list})

I think so:

my_dict = dict()
my_list = ["aaa", "bbb"]
for el in my_list:
    my_dict[el] = []

print(my_dict)
