A pure-Python, single-file, desktop To-Do List application built entirely with Tkinter (GUI) and SQLite (storage) from the standard library. It self-installs a couple of optional helper packages the first time you run it, so setup is just one command.

| Category | Details |
|---|---|
| Task fields | Title, description, category, tags, priority, due date, due time |
| Organization | Search, filter by status/priority/category, sort by due date/priority/created/alphabetical |
| Subtasks | Add a checklist inside any task; progress shown inline (3/5 subtasks) |
| Recurrence | Daily / Weekly / Monthly tasks auto-regenerate when completed |
| Reminders | Native desktop notifications ~15 minutes before a task is due |
| Bulk actions | Multi-select, mark complete, duplicate, delete |
| Safety net | Soft-delete with one-click Undo (Ctrl+Z) |
| Dashboard | Live stats bar: total / pending / completed / overdue + progress bar |
| Themes | Light and Dark mode, toggle anytime |
| Export | CSV and plain-text export of your full task list |
| Keyboard-first | Shortcuts for nearly every action (see below) |
| Storage | Local SQLite database (todo_data.db), created automatically next to the script — no server, no account, fully offline-capable |
Requires Python 3.8+ with Tkinter (bundled with most Python installs;
on Debian/Ubuntu you may need sudo apt install python3-tk).
python main.py
That's it. On first launch the app tries to silently install two small
optional packages (tkcalendar for a calendar picker and plyer for native
notifications). If you're offline or installation isn't possible, the app
detects this automatically and falls back to plain text-entry dates and
in-app popup reminders — every core feature still works.
Prefer to install dependencies yourself first?
pip install -r requirements.txt
python main.py
| Shortcut | Action |
|---|---|
Ctrl+N | New task |
Ctrl+F | Focus search box |
Ctrl+Z | Undo last delete |
Delete | Delete selected task(s) |
Space | Toggle complete on selected task(s) |
| Double-click a row | Edit that task |
| Right-click a row | Context menu (edit / complete / duplicate / delete) |
Ctrl+Enter | Save task (inside the editor window) |
Esc | Close the editor window |

NegaKnightV7, a sophisticated chess engine designed to play against a human opponent. It is implemented entirely in pure Python within a single file, and notably, it operates as a single-threaded application. It is recommended to use it with PyPy. Possibly, one of the strongest HCE engine written in single-file python.
