Complete Programs
This section's full programs 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 unzip and run), plus a full and portable

PCs or an app
on
Android).

PyEdit —
Edit Text. Run Code. Have Fun.
|
|
A Python/Tk text-editor and code-launcher GUI, that can be used as both
standalone program and library component. PyEdit can serve as your go-to
text editor, as well as a lightweight IDE that runs Python code and other
content.

features and
screenshots.

Frigcal
— Personal Calendar GUI; No Login Required
|
|
A Python/Tk calendar GUI, which stores your calendar entries in portable ICS
files that work across platforms and programs. With Frigcal, your calendar data
is your business, not something to be scanned and monetized by nosy companies.

features and
screenshots.

Mergeall
— Backup and Sync Your Stuff Your Way
|
|
A Python/Tk GUI+script program that backs up and syncs content folders quickly

features and
screenshots.

to snoops. For a quick preview, explore PyMaiGUI's
features and
screenshots.

Internet-Related Programs
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.

General-Purpose Programs
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.

Other Code, Notes, and Updates
Post-release program updates: off-page
Users of any of the five complete programs above should watch
this page
for 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 separate
support 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 following
suit.
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.
