Input/output
Bayani Gaba-gaba
A program that never asks its user anything, and never saves anything, is not much use. Real programs collect information from the person using them, check that information makes sense before acting on it, and keep a permanent record on disk so the data survives after the program closes. That is what input, validation and file handling give you.
In this lesson you will learn how to accept input from the keyboard and respond to it correctly, how to build validation that rejects impossible or unusable values, and how to read from and write to a text file. Every example is written in Python, one of the languages you can use for the Paper 2 practical programming exam.
Manufura
- Understand how to write code that accepts and responds appropriately to user input
- Understand the need for, and how to implement, validation
- Be able to write code that reads/writes from/to a text file
