The load_contacts function is responsible for reading the CSV file and transforming all the records into a list of Contact instances.

Each row read by csv.reader is returned as a tuple of strings, created by splitting the corresponding line using the comma delimiter. Since this tuple uses the same order as the parameters defined in the __init__ method of the Contact class, we can simply unpack it with the * operator. This code can be summarized in a single line using a list comprehension, as follows:

def load_contacts(self):
    with open("contacts.csv", encoding="utf-8", newline="") as f:
        return [Contact(*r) for r in csv.reader(f)]

There is no problem in returning the list within the with block, since the context manager automatically closes the file when the method execution finishes.
