#5 Python Variables, Naming & Dynamic Typing Explained | snake_case, Keywords & type()
🐍 Python Variables, Naming & Dynamic Typing Explained
In Python you don't declare a type before a variable — you just give it a name, assign a value, and Python figures out the rest! In this video we go deeper into how variables really work: naming rules, conventions, and the powerful concept of dynamic typing.
✅ What you'll learn:
✔️ Assignment with = (no type keyword needed)
✔️ Multiple assignment & swapping variables in one line (a, b = b, a)
✔️ snake_case — the naming convention every Python dev follows (PEP 8)
✔️ The naming rules Python actually enforces (break them = SyntaxError)
✔️ Reserved keywords you CAN'T use as names (all 35 of them)
✔️ The class_ trailing-underscore trick
✔️ Dynamic typing — how one variable can hold an int, then a str, then a list
✔️ Using type() to check what a variable holds right now
