Related: hosted elsewhere but also by the makers of the software on this page, the PC-Phone USB Syncapp syncs content folders between PCsand Android phones, uses Mergeall below, and is available on the Play store for Android and as a free download for PCs. For more info, tap the icon to the left, and see the prefaces added to subsumed pages like this. |

This section collects full programs that you can download and run on your macOS, Windows, and Linux PCs, as well as your Android smartphones and tablets. All are available as a self-contained macOS app, Windows exe, and Linux executable (which you simply install and run); plus a full and portable source-code package (which you run with your own Pythoninterpreter or Android app). For download locations and more details, click each program's icon or name to go to its main page.

A set of four Python/Tk desktop GUIs originally from the book PP4E—the PyCalc calculator, PyClock analog/digital clock,PyPhoto image viewer, and PyToe AI-based game—all upgraded, ported to macOS, and bundled as both executable and source. For a quick preview, see PyGadgets' screenshots. |
This section's programs pertain to Internet or web scripting. In the table below, click first-column links to go to main pages, and see Images for screenshots and Tools for coding subjects. All programs here are provided in source-code form and run on macOS, Windows, Linux, and other Python-friendly platforms. Most are run from command lines, though some run in web browsers or servers too, and many may be run in PyEdit's Run Code.
Among notables here: thumbspage creates web-page galleries for image folders; sitesearch adds search to websites;pylotto runs a web-based lottery;showcode formats text files for display; and genhtml generates a site's web pages from templates, inserting common parts automatically with HTML macros. Many of the programs here are used to build the site you are viewing.

This section's programs span application domains. In the table below, click first-column links to go to main pages, and see Images for screenshots and Tools for coding subjects. All programs here are provided in source-code form and run on macOS, Windows, Linux, and more. Most are run from command lines—in Terminal on macOS and Linux, Command Prompt on Windows, Termux on Android,PyEdit's Run Code, or other.
Among highlights here: deltas (a.k.a. Android Deltas Sync) syncs content from PCs to Android 11+ devices and others;iconify builds ".icns" and ".ico" files on both macOS and Windows; tagpix helps you organize your photo collections; and ziptools provides scripts and functions that zip and unzip archives anywhere, and fill in crucial support missing from Python's own zip module—symlinks, UTC times, cruft-file skips, and more.

This section's programs are smaller examples included primarily for Python learners. In the table below, click first-column links to go to main pages, and see Images for screenshots and Tools for coding subjects. Most examples here are supplements to material in my Python books and span application domains.
All examples here are provided in source-code form and run on macOS, Windows, Linux, and more, and all can be run from command lines, IDLE, PyEdit's Run Code, or other Python launching schemes.

Post-release application updates: off-page
Users of any of the five complete applications above should watch this pagefor announcements of updated releases, as well as new pointers and issues that arose after the apps' were published in 2017. That page's tips are updated regularly with new info.
Book Examples: see book pages
If you're looking for book example distributions, see the separatesupport page for your book and edition at this site. You can also find book example screenshots on the Programming Python gadgets page; some reflect early versions of major apps above.
Windows unzips caution
Though rare (and perhaps even moot today), Windows File Explorer's built-in zip support has been known to silently fail to extract some files in zip archives of the sort used to package many of the programs on this page. See this usage note for details and alternatives, including the Python-coded ziptools package above.
Ignore browser warnings for zipfiles
Some web browsers, including older Chromes on some platforms, have been seen to issue warnings when users try to download zipfiles. Although zipfiles can pose a security risk, those available here do not. This site has been spam- and virus-free since 1996. All its code is completely open source, safe to use, and free of advertising—despite the draconian measures being adopted by companies whose own products are not.
Ignore platform warnings for first runs
Some platforms also issue warnings the first time you run an independent developer's program which hasn't been officially sanctioned by the platform's owner. This includes apps here; see this note for more details and fixes. macOS, for example, still allows you to run apps that have not been registered with Apple (nor paid the requisite fee) but is making it increasingly hard—and perhaps even intimidating—to do so. Windows and Android are followingsuit. Alas, closed and proprietary seem the inevitable spawn of greed and monopoly.
Grant own-folder access to apps on macOS Sierra+
As an especially grievous extension to the preceding note, on macOS, non-store apps like those downloaded from this site may be denied write access to their own folders, unless you take action to enable it. The denial may produce reduced functionality or outright failures, though a simple app move will generally sidestep the issue. For complete work-arounds coverage—and an extra slice of righteous indignation—see the expanded support-page note here.
