Read file from parent directory in Python

Relative paths are relative to current working directory. If you do not want your path to be relative, it must be absolute.

from pathlib import Path
 
path = Path(__file__).parent / "../data/test.csv"
with path.open() as f:
    test = list(csv.reader(f))

from pathlib import Path
 
import pytest
 
@pytest.fixture()
def sfn_definition() -> str:
    # Read the step function definition from a file
    definition_path = Path(__file__).parent / "../step_function_definition.asl.json"
    with definition_path.open() as f:
        definition = f.read()
 
    return json.dumps(definition)
