Best way to accomplish 1field.char= value.field2.char "-" value.field3.char

Question

Might be a silly question and I apologize in advance.

Wondering how to do this or if it is even possible

So I have :

field1 = field.char

field2 = field.char
field3 = field.char
I want field1 to populate onchange of field2 and field3 separated by a "-"
Fields are in the same form and the same model.
example
Name(field1): John - Smith
First name(field2): John
Last name(field3): Smith

Sorry I think I figured it out but would appreciate feedback

@api.depends('firstname', 'lastname')
def _compute_full_name(self):
for record in self:
record.full_name = str(record.firstname) + "-" + str(record.lastname) if this is not appropriate please let me know

thank you!
