What is the default data type of items in list? Are they considered to be characters, integers, or somethings else?

Question

how does the items of a list are treated as a data type. as we can see the operations over two elements like for example a= [5,2,3,4,7]. a[0]+a[1]=7. so does elements are considered to be integers? if b=["hi", "hello", "how"], b[0]+b[2]=hihow. so how does items of a list are treated?

Answer 1

there is nothing like default data type of items
when you write a whole number, for example 3, it is an integer (int), when you put something in quotation marks, it will be a string "spam" when you write 3.7 or 8.0, it will be float
every element in list can have its own type
