Python [AppImages][APPIMAGE] are created using the `python-appimage` utility,
which is available on [PyPI][PYPI]. This utility can also be used to package
Python-based applications as AppImages using an existing AppImage and a recipe

!!! Caution
The `python-appimage` utility can only package applications that can be
directly installed with `pip`. For more advanced usage, one needs to extract
the Python AppImage and to edit it, e.g. as explained in the [Advanced
installation](index.md#advanced-installation) section. Additional details

installation inside an AppDir, and to build the corresponding AppImage. For

### Auxiliary tools
The `python-appimage` utility relies on auxiliary tools that are downloaded and
installed at runtime, on need. Those are [appimagetool][APPIMAGETOOL] for
building AppImages, and [patchelf][PATCHELF] in order to edit ELFs runtime paths
(`RPATH`). Auxiliary tools are installed to the the user space. One can get
their location with the `which` command word. For example,
installed on demand during application execution. These are
[appimagetool][APPIMAGETOOL], which is used to build AppImages, and
[patchelf][PATCHELF], which is used to edit runtime paths (`RPATH`) in ELF
files. These auxiliary tools are installed in the application cache. Their
location can be found using the `which` command. For example, the command
```bash
python-appimage which appimagetool
```
returns the location of `appimagetool`, if it has been installed. If not, the
`install` command word can be used in order to trigger its installation.

## Manylinux Python AppImages
AppImages of your local `python` are unlikely to be portable, except if you run
an ancient Linux distribution. Indeed, a core component preventing portability
across Linuses is the use of different versions of the `glibc` system library.
Hopefully, `glibc` is highly backward compatible. Therefore, a simple
work-around is to compile binaries using the oldest Linux distro you can afford
to. This is the strategy used for creating portable AppImages, as well as for
distributing Python site packages as ready-to-use binary [wheels][WHEELS].

Therefore, a simple workaround is to compile binaries using the oldest Linux
distribution you can. This strategy is used to create portable AppImages and to
distribute Python site packages as ready-to-use binary [wheels][WHEELS].
The Python Packaging Authority (PyPA) has defined standard platform tags for
building Python site packages, labelled [manylinux][MANYLINUX]. These build
platforms are available as Docker images with various versions of Python already
installed. The `python-appimage` utility can be used to package those installs
as AppImages. For example, the following command
building Python site packages labelled [Manylinux][MANYLINUX]. These build
platforms are available as Docker images, with different versions of Python
already installed. The `python-appimage` utility can be used to package these
installations as AppImages. For example, the following command
```bash
python-appimage build manylinux 2014_x86_64 cp310-cp310
python-appimage build manylinux 2014_x86_64 cp313-cp313
```
should build an AppImage of Python 3.10 using the CPython (_cp310-cp310_)
install found in the `manylinux2014_x86_64` Docker image.
should build an AppImage of Python __3.13__ using the CPython (__cp313-cp313__)
installation found in the `manylinux2014_x86_64` Docker image.
!!! Note
Docker needs to be already installed on your system in order to build
Manylinux Python images. However, the command above can be run on the host.
That is, you need **not** to explictly shell inside the manylinux Docker
image.
From version `1.4.0` of `python-appimage` onwards, Docker is **no longer**
required to build the Manylinux Python images. Cross-building is also
supported, for example producing an `aarch64` Python image from an `x86_64`
host.
!!! Warning
Creating multiple Manylinux Python images can significantly increase the
size of the application cache. This can be managed using the
`python-appimage cache` command.
!!! Tip
A compilation of ready-to-use Manylinux Python AppImages is available from
the [releases][RELEASES] area of the `python-appimage` [GitHub
A compilation of ready-to-use Manylinux Python AppImages is available in the
[releases][RELEASES] section of the `python-appimage` [GitHub
repository][GITHUB]. These AppImages are updated weekly, on every Sunday.
!!! Tip
Instead of an AppImage, the `python-appimage build manylinux` command can
produce either an `AppDir` or a bare tarball (i.e. without the AppImage
layer) of a Manylinux Python installation. See the `-b` and `-n` command
line options for more information.

installation. In this case, you may wish to refer to the initial AppImage
[Packaging Guide][APPIMAGE_PACKAGING], and use alternative tools such as
[linuxdeploy][LINUXDEPLOY].
However, `python-appimage` can still be of use in more complex cases by
extracting its AppImages to an AppDir, as discussed in the [Advanced
installation](index.md#advanced-installation) section. The extracted AppImages
contain a relocatable Python runtime, that can be used as a starting base for
building more complex AppImages.
However, `python-appimage` can still be useful in more complex cases, as it can
generate a base AppDir containing a relocatable Python runtime (e.g., using the
`-n` option). This can then serve as a starting point to create more complex
AppImages.
!!! Tip
In some cases, a simple workaround to missing external libraries can be to
fetch portable versions of those from a Manylinux distro, and to bundle them
under `AppDir/usr/lib`. You might also need to edit their dynamic section,
e.g. using [`patchelf`][PATCHELF], which is installed by `python-appimage`.

Python `AppDirs` follow the [Manylinux][MANYLINUX] installation scheme.
Executable scripts are installed under the `AppDir/opt/pythonX.Y/bin`
