String Concatenation
Domain: Programming Fundamentals
🎯 Motivation
You often need to join text together - combining a first name and last name, or building a message.
📋 Concrete Example
'Hello, ' + name + '!' joins the strings. In Python, f-strings are easier: f'Hello, {name}!'
🔗 Analogy
Gluing paper strips together - each piece of text is a strip, and + is the glue that joins them into one long strip.
