pypeh

pypeh is a lightweight ETL and data-ops toolkit for Personal Exposure and Health (PEH) data.

It helps you:

• work with PEH-model resources in Python
• load/transform/validate PEH study data
• support FAIR data workflows (findable, accessible, interoperable, reusable)

The toolkit is built to interact with the PEH model from PARC:

• https://github.com/eu-parc/parco-hbm

Install

Core package:

uv pip install pypeh

With dataframe adapter extras (Polars-based workflows):

uv pip install "pypeh[dataframe-adapter]"

Basic Usage

from pypeh import Session

# Start a session
session = Session()
# Load PEH model resources (e.g. YAML configs) into cache
session.load_persisted_cache(source="config")
# Load tabular data as a DatasetSeries using a DataImportConfig from cache
data_import_config = session.cache.get("<data_import_config_id>", "DataImportConfig")
dataset_series = session.load_tabular_dataset_series(
    source="my_data.xlsx",
    data_import_config=data_import_config,
)

From there you can use adapters for:

• validation
• enrichment (derived variables)
• aggregation
• export/persistence
