Caps Lock
Practise on real Python code: functions with type hints, list and dict comprehensions, f-strings, dataclasses, exceptions, file handling with pathlib, requests, asyncio and pytest-style tests. Indentation is set for you, so you can focus on the characters that slow you down.
Colons at the end of def, if and for lines, underscores in snake_case names, square and curly brackets in comprehensions and the quotes and braces of f-strings. Klava tracks your accuracy on symbols separately from letters and builds a personal drill from the ones you miss.
Switch to the Django set for models, views and URLs, generate endless Python code, or practise other languages.
