Answer 1

You were very close. There were actually 2 errors.

there were 3 columns (in the first row) and you are unpacking 2 values.
the append() takes 1 dict, but you were passing 2 dicts.

with the error fixed, this works:

import csv

students = []

f = "C:\test\test_file.csv"
with open(f) as file:
    reader = csv.reader(file)
    for name, home in reader:
        students.append({"name": name, "home": home})


for student in sorted(students, key =lambda student:student["name"]):
    print(f"{student['name']} is from {student['home']}")

returns this:

Draco is from  Malfoy manor
Harry is from  Number
Ron is from  The burrow
