Use Python’s built-in string methods and regex to split by whitespace, custom delimiters, limits, line breaks, or into characters.

Use sorted() to return a new sorted list or list.sort() to reorder in place; both support key= and reverse= for custom order.

Use slicing for speed, reversed()+join for readability, and grapheme-aware logic for correct emoji and accent handling.

Use Python 3’s print() function to output text, with quick steps for scripts, the interactive shell, online IDEs, and Windows/macOS/Linux terminals.

Set up pip the right way, isolate dependencies with venv, and use reliable commands for versions, extras, and advanced installs.

Execute functions with parentheses, pass arguments correctly, capture return values, and invoke functions by name when needed.
