A python basic question

Question

the result of this code prints >HI!
but i didnt called the function, can anyone interpret what is happening here?
def some_func():
print("Hi!")

var = some_func()
print(var)

Answer 1

You called it via the variable "var".

Answer 2

i thought var only contains the return value,

Answer 3

If there was a return value, var would be assigned to it. But the entire loop would have been checked, and it would have printed hi either way.
