Underscores in Python often sneak into variable names like hidden ๐๐ค characters. Use ๐๐๐ง when explaining code style or conventions, or ๐๐๐ while debugging scripts that refuse to run. Dropping ๐๐๐ fits tutorials or documentation chats, while ๐๐๐ highlights searching through snake_case variables. These combos fit perfectly when youโre deep in coding or sharing tips on Pythonโs quirks.
