Selected Lesson

Setup, First Program, and Input

Get the learner running code immediately and build confidence with a first reusable function.

LeetCode style

Create a function greet(name) that returns a string. Read a name with input(), call the function, and print the result.

Example input

name = "Asha"

Example output

Hello, Asha!

Concept

A function packages a reusable idea. Here, greet(name) takes input and returns a friendly string.

Guided Example

def greet(name):
    return f"Hello, {name}!"

print(greet("Asha"))

1. Warm-up

Show the goal, prerequisites, and why this topic matters in the real world.

2. Concept

Explain the idea in simple language, then connect it to Python syntax.

3. Guided example

Walk through a solved example before the student touches the code.

4. Mini-practice

Use tiny edits or fill-in-the-blank tasks to check understanding fast.

5. Challenge

Present a LeetCode-style question with hidden-test-style thinking.

6. Review

Explain time, space, edge cases, and a better version if available.

7. Reflection

Ask the learner to explain the solution in their own words before unlocking the next lesson.

Use print() and input() without syntax errors.

Return a string from a function.

Separate the function logic from the I/O logic.

-Add a second prompt for favorite color.

-Format the output with an f-string.

-Reject empty input with a friendly message.

Start with def greet(name: str) -> str: and return the greeting.

Keep the function pure; read input outside the function.

Use f"Hello, {name}!" for the final string.

Chapter focus: Install tools, run Python, and write your first program.

Reflection prompt: Why is it better to return the greeting from a function instead of printing directly inside it?
