Is there an example repo with multiple python packages which each have individual tests? something like the below for structure package1 package1 tests readme.md

The python example project has a structure of

├── helloworld
│   ├── BUILD
│   ├── __init__.py
│   ├── greet
│   │   ├── BUILD
│   │   ├── __init__.py
│   │   ├── greeting.py
│   │   ├── greeting_test.py
│   │   └── translations.json
│   ├── main.py
│   └── translator
│       ├── BUILD
│       ├── __init__.py
│       ├── translator.py
│       └── translator_test.py
├── BUILD
├── LICENSE
├── README.md
├── mypy.ini
├── pants
├── pants.ci.toml
├── pants.toml
├── pants_from_sources
├── python-default.lock
└── requirements.txt

greet

and

translator

both have individual tests with associated BUILD files. Does that help?

hm, thats more of a "single package", right? you have a single python package called

helloworld

in this case. What if i want to have multiple? for example having

greet

and

translate

as two packages;

from greet import X

instead of

from helloworld.greet ...

. Is there a recommended structure for that? Right now I do:

greet
  - greet 
     - greeting.py
   - tests
   - README.MD 
   - pyproject.toml
   - BUILD
translate
  - translate
     - translate.py
   - tests
   - README.MD 
   - pyproject.toml
   - BUILD

is that the right way?

I think what you are asking is how to import local packages in the same way one imports a 3rd party package? Pants uses source roots to indicate which directories should be treated as import targets (libraries, etc). I've modified the python example project to demonstrate. You can see the modifications using git

git diff HEAD~

once you've unzipped the attachment. The monorepo structure demonstrated is:

├── helloworld
│   ├── BUILD
│   ├── __init__.py
│   └── main.py
├── libs
│   ├── greet
│   │   ├── BUILD
│   │   ├── __init__.py
│   │   ├── greeting.py
│   │   ├── greeting_test.py
│   │   └── translations.json
│   └── translator
│       ├── BUILD
│       ├── __init__.py
│       ├── translator.py
│       └── translator_test.py
├── pants.toml

The change to

root_patterns

in

pants.toml

enables the libs to be imported directly. I hope this helps
