Coding – Step 10 – Python from Zero – Lesson 1: Variables, Input, and Simple Logic

Welcome to the first real Python lesson — where you’ll build a mini console app using real code, logic, and user input.

No theory-only content here: we learn by writing and running code immediately.

📚 What You’ll Learn

✅ How to use print() and input()
✅ How to store and use variables
✅ How to check if a value exists (if condition)
✅ How to work with text and numbers (str, int)
✅ How to create a basic interactive program

🧰 What You Need

If you haven’t already:

1. Install Python
2. Recommended editor: Thonny for total beginners
   (or Notepad++ if you prefer editing + terminal)

🎯 What Are We Building Today?

A simple Python script where:

• The user enters their name
• Then lists 3 things they want to do today
• The app checks what’s empty and warns if nothing was typed
• Then prints a clean, stylized summary

It’s basic, but real logic — and a perfect starting point.

🔣 Let’s Break It Down – Step by Step

🪧 Step 1 – Greet the user

print("Welcome to your personal To-Do Assistant!")

Shows a welcome message in the terminal.

🙋 Step 2 – Ask for their name

name = input("What's your name? ")

This reads what the user types and stores it in a variable called name.

✅ Step 3 – Confirm name

if name.strip() == "":
    print("You didn't enter a name... but we'll continue anyway!")
else:
    print(f"Nice to meet you, {name}!")

Here we’re using a conditional statement (if) to check if the user skipped the name.
.strip() removes spaces and tabs — so " " becomes "".

📝 Step 4 – Ask for 3 tasks

print("\nEnter 3 things you want to do today:")

task1 = input("1: ")
task2 = input("2: ")
task3 = input("3: ")

We’re storing 3 different tasks in 3 separate variables.
We’ll use lists in Lesson 2 — but this is a great start.

📋 Step 5 – Display results

print("\nHere’s your personalized To-Do List:")

if task1.strip(): print(f"🟢 1. {task1}")
else: print("🔴 1. [Empty]")

if task2.strip(): print(f"🟢 2. {task2}")
else: print("🔴 2. [Empty]")

if task3.strip(): print(f"🟢 3. {task3}")
else: print("🔴 3. [Empty]")

We check whether each task was actually typed.
This builds conditional output, depending on what the user entered.

🧼 Step 6 – Thank and exit

print("\nYou're ready to take action. Good luck!")

Simple closing message.

🧾 Full Code Recap (Copy-Paste Ready)

print("Welcome to your personal To-Do Assistant!")

# Get the user's name
name = input("What's your name? ")

# Check if name is empty
if name.strip() == "":
    print("You didn't enter a name... but we'll continue anyway!")
else:
    print(f"Nice to meet you, {name}!")

# Ask for tasks
print("\nEnter 3 things you want to do today:")

task1 = input("1: ")
task2 = input("2: ")
task3 = input("3: ")

# Show the list
print("\nHere’s your personalized To-Do List:")

if task1.strip(): print(f"🟢 1. {task1}")
else: print("🔴 1. [Empty]")

if task2.strip(): print(f"🟢 2. {task2}")
else: print("🔴 2. [Empty]")

if task3.strip(): print(f"🟢 3. {task3}")
else: print("🔴 3. [Empty]")

print("\nYou're ready to take action. Good luck!")
