In Python can you add elements from a list to the values of a dictionary?

April 29, 2022

I am trying to add the elements of a list of list to the values of a dictionary.

I have created a list with elements from a file that looks like this:

list_of_lists = [[966], [1513, 2410], [2964, 1520, 604]....]

I am trying to add this list to a dictionary that I have made to look like this:

{'Youngstown': ['OH', 4110, 8065, 115436], 'Yankton': ['SD', 4288, 9739, 
12011], 'Yakima': ['WA', 4660, 12051, 49826]....]

I have tried the following code:

 x = 1
 for x in d2.values():
     d2.append(list_of_list)
 print(d2)

I am not even sure that this is something that is possible, but I am trying to get the dictionary to be:

{'Youngstown': ['OH', 4110, 8065, 115436], 'Yankton': ['SD', 4288, 9739, 
12011, [966]], 'Yakima': ['WA', 4660, 12051, 49826, [1513, 2410]]....]

>Solution :

I know there are more ways to do that, But I think this is more readable and understandable code.

list_of_lists = [[966], [1513, 2410], [2964, 1520, 604]] 

dict_ = {'Youngstown': ['OH', 4110, 8065, 115436], 'Yankton': ['SD', 4288, 9739, 
12011], 'Yakima': ['WA', 4660, 12051, 49826]}

i = 0
# list(dict_.items())[1:] is the list of all keys and values except first one.
for key,value in list(dict_.items())[1:]:
    dict_[key] = value+[list_of_lists[i]]
    i+=1
print(dict_)
