Study Notes

Course Overview

The course covers the scope of using files in Python, including file types, modes of operation, and data persistence.

File Types

There are two key types of files: text files and binary files, with the main difference being the way data is stored and retrieved.

Lecture L.14

The theme of Lecture L.14 is the use of files in Python.
The learning objective is to understand the importance of files for data persistence and data sharing.

Text Reference

The course text reference provides further information on using files in Python.

Importance of Files

Files are vital for data persistence, as they allow data to be stored and retrieved even after a program terminates.
Files facilitate data sharing, enabling data to be easily shared and accessed by multiple users and programs.

Advantages of Files

The main advantage of using files for large data handling is efficient storage and retrieval.
Binary files are used for storing large amounts of data, while text files are used for storing human-readable data.

File Operations

Files in Python have various modes of operation, including read, write, and append.

Data Storage

Storing data in non-volatile form, such as on a hard drive, ensures data persistence even when power is turned off.
