Indexing and Slicing Python Strings
Accessing characters, whether they are single or multiple, is an essential skill for working with strings in any programming language. In Python, we do this by indexing and slicing the string. In this hands-on lab, we'll go through writing some code to demonstrate that we understand how to use indexing and slicing by printing out different pieces of information about a string back to the user. To feel comfortable completing this lab, you'll want to be familiar with the following: * Working with string literals: Watch the "Strings and String Operators" video from the Certified Entry-Level Python Programmer Certification course. * Indexing and slicing strings: Watch the "String Indexing and Slicing" video from the Certified Entry-Level Python Programmer Certification course. * Printing to the screen: Watch the videos from the "Input and Output Operations" section of the Certified Entry-Level Python Programmer Certification course.

Create the string-info.py Script and Take User Input
-
We want to be able to execute our script, so to begin create an empty script named
string-info.py
with a shebang and make it executable:$ echo '#!/usr/bin/env python3.7' > string-info.py $ chmod +x string-info.py
-
Create a script that asks for user input, store it as the
message
variable, and print a handful of lines to the screen. Let's take the user input now.
