Python 1 Module 7 Lesson 2 Banner

Overview

The student will consider the following...

Sometimes as programmers we must be able to extract subsets of a string to use in other parts of our program. For example if a user is asked to enter their full name as first name (space) last name, and our program will convert the name into last name (comma) first name format, then we would need to get a subset of the entered string. In Python the process of getting subsets of strings is known as slicing. We can use a variety of slicing techniques to get multiple subsets of a string.

In this lesson, students will learn how slicing allows them to select multiple string values at once from a given string.

Objectives

The student will be able to...

use slicing to select a set of values from a string
