Minecraft's command blocks allow players to automate console commands, but they are hard to find, so this guide shows how to get them.

You can get a command block in your Minecraft Java or Bedrock world using cheats and a special chat command.

Minecraft: Education Edition can now teach kids how to code with the new Code Builder tool and the 'Agent', an in-game robot. Mojang will add Command Blocks in Education Edition later this year.

This is possible to a degree by using in-game commands made available by enabling cheats. However, this command won't necessarily change a biome's blocks, but an area's biome classification.
