Python is a programming language that lets you work more quickly and integrate your systems more effectively.

You can easily add it to your Lando app by adding an entry to the services top-level config in your Landofile.

Supported versions

Legacy versions

You can still run these versions with Lando but for all intents and purposes they should be considered deprecated eg YMMV and do not expect a ton of support if you have an issue.

Patch versions

Not officially supported!

While we allow users to specify patch versions for this service they are not officially supported so if you use one YMMV.

To use a patch version you can do something like this:

    type: python:3.5.6

But make sure you use one of the available patch tags for the underlying image we are using.


Here are the configuration options, set to the default values, for this service. If you are unsure about where this goes or what this means we highly recommend scanning the services documentation to get a good handle on how the magicks work.

Also note that the below options are in addition to the build steps and overrides that are available to every service.

    type: python:3.7
    port: 80
    ssl: false
    command: tail -f /dev/null

Specifying a command

Note that if you do not define a command for this service it will effectively be a "cli" container eg it will not serve or run an application by default but will be available to run python commands against.

If you want to actually launch a python application consider setting the command to something like:

    type: python
    command: /app/my-server.py

Setting a port

While we assume your python service is running on port 80 we recognize that many python app's also run on port 8000 or otherwise. You can easily change our default to match whatever your app needs.

    type: python
    port: 8000

Using SSL

Also note that ssl: true will only generate certs in the default locations. It is up to user to use the certs and secure port correctly in their application like as in this python snippet:

    type: python
    ssl: true
    port: 443
// Starting HTTPS server
httpsd = HTTPServer(('', 443), myHandler)
httpsd.socket = ssl.wrap_socket (httpsd.socket, server_side=True, certfile='/certs/cert.crt', keyfile='/certs/cert.key')
print('starting https server...')

Path Considerations

Lando will set the following PATH hierarchy for this service.

  // Line directly below is your PYTHONUSERBASE

This is useful to note if you are not using absolute paths in any tooling routes and are getting the unexpected version of a particular utility.
