Question

Hi folks Quick question I ve noticed that sometimes I need to add `sources= py ` in my `python library` target in order for my `pex binary` in the same BUILD to run successfully or else it would `ImportError No module named path to entry point` but in some other cases I don t need that `source= py ` for things to work What s the magic here

targets have default sources globs which you can see in their help see ``` pants help python library```

witty-crayon-22786 · Answer

```sources type Iterable str | None default py pyi test py test py tests py conftest py test pyi test pyi tests pyi A list of files and globs that belong to this target Paths are relative to the BUILD file s directory You can ignore files globs by prefixing them with ` ` Example `sources= example py test py test ignore py ` ```

You shouldn t need that unless does one of the relevant source files match `test py` or ` test py`

in the case of `python library` it avoids grabbing what look like test files
