Most current systems (default Debian/Ubuntu, recent macOS) install Python only as `python3`, with no bare `python` on PATH, so learners who copied `python cli.py ...` into their host shell hit "command not found". Convert host-shell `python <cmd>` -> `python3 <cmd>` across module/lab READMEs, lab `.py` docstrings & usage strings, blog posts, lab prompt and instruction files, the M04 verify.sh message, and the M10/M24 lab patches. Module 01's convention note (and its blog/02 mirror) is rewritten so `python3` is canonical and `python` is the documented fallback. Stop-lines respected: Docker image tags (`python:3.12-slim`), `.venv/.../python` and `...\.venv\Scripts\python.exe` paths, the M20 `"command": "python"` teaching example and surrounding venv prose, container-internal invocations (M16/M18 Dockerfiles, M16 README `docker run` examples), and CI-workflow `run:` steps fed by `actions/setup-python` / `image: python:3.12` are left as `python` on purpose. pip was left out of scope: most occurrences are prose or CI/container-internal, and `pip3` does not fix the PEP 668 externally-managed-environment refusal that the course already addresses with venvs. The M01 note is worded to stay consistent with bare `pip` (use whichever pip pairs with your Python). Build (tools/build_wiki.py) and tools/check.sh both pass.

# Agent A prompt: the `wipe` command
|
|
|
|
Paste this into the AI session you've pointed at the `tasks-app-wipe` worktree folder.

|
|
Add a `wipe` command to this task app that removes **all** tasks.
|
|
|
|
- Put the deletion logic on `TaskList` in `tasks.py` (a `wipe()` method that empties the list),
|
|
and wire a `wipe` command into the dispatch in `cli.py` that calls it and saves.
|
|
- Running `python3 cli.py wipe` should empty the list and print a short confirmation like
|
|
`wiped all tasks`.
|
|
- After `wipe`, `python3 cli.py list` should print `(no tasks yet)`.
|

Make the change, then stop. I'll review the diff, then have you commit it on this branch.
