Echo

A minimalistic Python wheel that echoes back the arguments passed to it.

Getting started

1. pyenv install if you're using pyenv to manage Python versions
2. script/build builds the Python module into a wheel
3. script/deploy copies the wheel to DBFS using the default databricks-cli profile

Entrypoints

Three entrypoints are defined:

• echo = echo:main (takes no arguments and echoes sys.argv[1:] back)
• echo_with_args = echo:main_with_args (takes *args, **kwargs and echoes back everything)
• parse_with_args = echo:parse_with_args (takes *args, **kwargs, parses with ArgumentParser and echoes back everything)

echo_with_args takes optional *args and **kwargs arguments that can be passed directly.

Usage

CLI

$ python -m echo foo bar
sys.argv[1:] ['foo', 'bar']

$ echo_with_args foo bar
args ()
kwargs {}
sys.argv[1:] ['foo', 'bar']

$ parse_with_args --foo=bar --throw=nothing args Namespace(args=[], throw='nothing') leftovers ['--foo=bar']
