Lesson 02 of 55
8 mins readPython Syntax Rules, Comments & Identifiers
In Plain English
Lua syntax is clean and concise. Semicolons are optional between statements, and comments are denoted with double hyphens `--`.
Deep Dive: How It Works
Optional Semicolons: Semicolons `;` can be used to separate statements on the same line, but are optional.
Single-Line Comments: Prefix comments with `--`.
Multi-Line Comments: Enclose block comments with `--[[ ... ]]`.
Case Sensitivity: Lua is case-sensitive (`Name`, `name`, and `NAME` are distinct).
Core Rules to Remember
Hyphen Comments: Use `--` for single line and `--[[ ... ]]` for blocks.
Case Sensitive: Identifiers and keywords are strictly case sensitive.
