[PYTHON] Create a new dict that combines dicts

Like the list

dict_a + dict_b

Even if you write, you can not combine dictionaries, so I thought that I had to write a loop and combine it by myself, but this is one shot.

{**dict_a, **dict_b}

(Because I was told in the comments)

dict_a += dict_b

If you want to do something

dict_a.update(dict_b)

I will meet you. I'm wondering if both + and + = operators are okay.
