Python Quiz 🐍 Before you scroll, check that if one more time. 🐍 You type "no". What does this code print? A) Continuing B) Maybe next time! C) An error What’s your pick? #Python #LearnPython #PythonTips #100DaysOfCode #CodeNewbie

🐍 Make It Pythonic Some string tricks look clever at first. Then someone reads the code later and needs a small map. 😅 Instead of writing: name = "sara" message = ("Hi, " + name.title() + "!").replace("Hi", "Welcome") ✨ Write it the Pythonic way: name = "sara" display_name = name.title() message = f"Welcome, {display_name}!" The second version uses simple steps with clear names. It is easier to read, easier to change, and easier to trust. Make it short when you can, clear when you must. 🐍 #Python #PythonCode #Coding #Programming #CodeNewbie #100DaysOfCode #PythonTips

🐍 Python Tip: When to Use Separate ifs Instead of elif Should you use elif or another if? 🐍 If you want both actions to happen when both conditions are true, use two separate ifs. Here’s a little example 😊 number = 6 if number % 2 == 0: print("Divisible by 2!") elif number % 3 == 0: print("Divisible by 3!") You’ll only see “Divisible by 2!” — Python skips the elif once the first condition is true. But 6 is divisible by both! Give each condition its own if: if number % 2 == 0: print("Divisible by 2!") if number % 3 == 0: print("Divisible by 3!") Use elif to choose one branch. Use separate ifs when multiple branches may need to run. #Python #PythonTips

Every Python beginner meets this error at some point: AttributeError: 'NoneType' object has no attribute 'upper' Here is the tricky part. Python points at the line where the None was used, but the real mistake is usually somewhere else. Like this: def make_greeting(name): greeting = "Hello, " + name print(greeting) message = make_greeting("Ada") print(message.upper()) Python points at the last line. But the bug is in make_greeting: it prints the greeting instead of returning it, so it quietly hands back None. Finding that by hand is the "trace back" work every tutorial tells you to do. There is now a small tool that does it for you. Add two lines at the top of your program and the error message gains a few extra lines: which function returned the None, on which line, why, and how to fix it. It's called nonetrace. pip install nonetrace pypi.org/project/nonetrace/ #Python

🐍 Make It Pythonic When you need both the position and the item, do not make Python walk through indexes first. Instead of writing: fruits = ["apple", "banana", "mango"] for i in range(len(fruits)): print(i, fruits[i]) ✨ Write it the Pythonic way: fruits = ["apple", "banana", "mango"] for i, fruit in enumerate(fruits): print(i, fruit) enumerate() gives you two things at once: the index and the item. So the loop becomes easier to read. #Python #PythonCode #Coding #Programming #CodeNewbie #100DaysOfCode #PythonTips

Many Python accounts and educators on YouTube built their audiences by sharing Python tutorials, tips, libraries, and tools… then packed their bags for AI. Python is still here, waiting for a post or two. @driscollis, still here keeping Python going 🐍 What's your take on everyone else moving on? #Python #PythonTips #100DaysOfCode

Small thing I made: guardlist. You know how modifying a list inside a for loop silently skips items? Python protects dicts from that but not lists. GuardedList fixes that with a proper error message. pip install guardlist pypi.org/project/guardlist/ #Python #Python #Pygame #Coding #Programming #PythonTips @driscollis

b. {'a': 1, 'b': 99, 'c': 4} A small related detail: {'b': 99, 'b': 7} Python keeps only the last value for the duplicate key, so this becomes {'b': 7}.

🐍🎮 Pygamers, what do you think happens here? Look carefully at the order of these lines: screen = pygame.display.set_mode((600, 400)) pygame.draw.circle(screen, "white", (300, 200), 60) screen.fill("green") pygame.display.update() What will appear on the screen? A) A white circle on a green background B) Only a green background C) Only a white circle D) An error What’s your answer? 👇 #Python #Pygame #Coding #Programming #PythonTips

Thanks for asking! Honestly, it assumes a little Python already — the questions ask you to read a snippet and predict what it does, so a complete beginner would be guessing. But World 1 starts at the basics, and if you sit with him for it, it could be a good way in — he plays, you explain. It's free, so worth a try together. Let me know how he finds it!

Thanks Mike, that's very kind 🙏 The final Dragon of Truth battle took the longest to build — would love to hear what you think if you play it.
