Case
- Goal
- Pin python-dotenv master disable switch (PYTHON_DOTENV_DISABLED), override precedence on os.environ vs variable interpolation, and dotenv_values override divergence HOW
- Packages
- python-dotenv 1.2.2
- Environment
- python
- Created

Contract
- PYTHON_DOTENV_DISABLED set to truthy values ('1', 'true', 'yes', 't', 'y') causes load_dotenv to return False and load nothing into os.environ, while dotenv_values continues to parse files
- load_dotenv with override=False (default) preserves existing os.environ keys and resolves variable expansions (${VAR}) using os.environ values rather than .env file definitions
- load_dotenv with override=True overwrites existing os.environ keys and resolves variable expansions using .env file definitions
- dotenv_values always evaluates variable expansions using file values regardless of existing os.environ definitions, diverging from load_dotenv(override=False)
- interpolate=False disables variable interpolation and preserves ${VAR} and ${VAR:-default} as raw string literals
- unset variable parameter expansion (${UNSET:-default}) evaluates to default while unset variable without default (${UNSET}) evaluates to empty string
- keys without values ('KEY=') resolve to empty string ('') whereas valueless keys ('KEY') resolve to None in dotenv_values and are skipped by load_dotenv
