Question

Write a function that writes a structure to disk and then reads it back and display on screen.

Answer 1

A Python structure such as a dictionary can be stored and retrieved using the pickle module.

import pickle

def write_read_structure():
    record = {
        "code": 101,
        "name": "Notebook",
        "price": 50,
        "quantity": 10
    }

    with open("item.dat", "wb") as file:
        pickle.dump(record, file)

    with open("item.dat", "rb") as file:
        retrieved_record = pickle.load(file)

    print(retrieved_record)

write_read_structure()
