Strings & I/O: Worked Reasoning
≈ 25 minWorked Reasoning
Make each reasoning step visible: identify the knowns, choose the governing idea, apply it and check the result.
This extension applies that lens specifically to Strings & I/O.
A string is text. You can join strings with + (concatenation) and measure them with len():
greeting = "Hello, " + name n = len("hello") # 5
Strings have handy methods: "cape town".upper() → "CAPE TOWN", " hi ".strip() → "hi".
print(...) sends text to the screen; input(...) reads a line the user types (returns a string).
Python Foundations — Worked Reasoning: Write a function greet(name) that returns the string "Hello, " followed by the name. For example greet("Zanele") returns "Hello, Zanele".
