What's Next: Stepping into Python 3 Programming

Python for Absolute Beginners · Lesson 17

What you’ll learn

• Everything you can now do, collected in one place
• How this course connects to Python 3 Programming
• Which of its lessons will feel familiar, and which will be new
• How to keep learning after this course ends

What you can do now

• Run Python and use IDLE (Lessons 2–3): install, open the shell, save and run program files
• Store values (Lesson 4): variables, naming rules, updating a value from its old self
• Do arithmetic (Lesson 5): integers, floats, division, remainders, powers, order of operations
• Handle text (Lesson 6): strings, quotes, joining, repeating, length, and positions
• Decide and repeat (Lessons 8–10): booleans, comparisons, if chains, for loops, and while loops

What you can do now, continued

• Draw with code (Lesson 11): Turtle shapes, colors, and loops you can see
• Organize data (Lessons 12–13): lists by position, dictionaries by label
• Reuse code (Lesson 15): functions with parameters and return values
• Build a complete program (Lesson 16): a guessing game with random numbers, player input, hints, and a score count

The recap program

name = "Coder"
score = 0
for round in range(3):
    score = score + 10
    print(name + " has " + str(score) + " points.")
if score >= 30:
    print("Finished!")

Coder has 10 points.
Coder has 20 points.
Coder has 30 points.
Finished!

Every line uses something from this course, and nothing else. If you can read it line by line, you have genuinely learned the foundations.

Stepping into Python 3 Programming

• This course was designed as the on-ramp to Python 3 Programming, and the step is deliberately smooth
• You already know its opening ground: setup, IDLE, printing, variables, numbers, strings, comparisons, decisions, and loops
• Its opening lessons will therefore move faster for you than for someone starting cold
• You will recognize the ideas and spend your energy on the new material instead of the setup

New ground ahead

• Files — reading from and writing to files, so programs can remember things between runs
• Object-oriented programming — bundling data and the code that works on it into objects of your own design
• Networking — programs that talk to other computers: fetching web pages, sending requests, running simple servers
• None of that requires anything you do not already have — the same thinking, applied to larger problems

How to keep learning

• Change working programs: take the guessing game and alter one thing at a time
• Read error messages: they point at the exact problem — the computer helping you, not punishing you
• Build small things often: a calculator, a quiz game, a to-do list, a Turtle drawing
• Small finished programs beat big unfinished ones, every time
• If you feel stuck, go back one lesson, not back to the start

Hands-on exercise

• Run the recap program above and explain each line out loud, in your own words
• Extend it: add a dictionary holding your name and score, and print a final message built from it
• Write down the first thing you want to build next — a game, a tool, or a drawing — and which lessons' ideas it will need
• Open the Python 3 Programming course and read its first lesson; mark every idea you already recognize

Key takeaways

• You now command the foundations: setup, variables, numbers, strings, decisions, loops, Turtle, lists, dictionaries, functions, and a complete game.
• Python 3 Programming builds directly on this course, with the same IDLE toolchain — its opening lessons will feel familiar.
• New ground there: files, object-oriented programming, and networking.
• Keep learning by changing working programs, reading error messages, and building small things often.
• You started with zero experience and finished with a real program. That is what learning to code looks like.
