You need to change the open mode to text. I came upon this on the documentation, and this example is not working:

https://docs.python.org/3.11/library/collections.html#namedtuple-factory-function-for-tuples-with-named-fields :

EmployeeRecord = namedtuple('EmployeeRecord', 'name, age, title, department, paygrade')
import csv
for emp in map(EmployeeRecord._make, csv.reader(open("employees.csv", "rb"))):
    print(emp.name, emp.title)
