Python create dictionary with defined key and list of values with comprehension

If I have the following list of ids:

id_numbers = ['08a592a1-5a40-46b7-b9b3-b3a1e6bfdb9f', 'a31017f7-13b4-401c-81ca-fd57042bc181']

I can add these id numbers as values of a defined key "id_numbers" in a new dictionary using the following:

catalogue_ids = {"id_numbers": []}

for item in id_numbers:
    catalogue_ids["id_numbers"].append(item)

I was wondering if there is a dictionary comprehension way of doing the same thing?

Solution 1:

catalogue_ids = {"id_numbers": [item for item in id_numbers]}

There's no need to use list/dictionary comprehensions. You can simply assign the id_numbers variable to the dictionary element.

catalogue_ids = {"id_numbers": id_numbers}
