Python Environment Lifecycle & Constraints

Operational Realities of Virtual Environments

Portability & Isolation Limits

Structural Constraints

• Hardware Bound: Compiled strictly for the host OS and CPU architecture.

• Path Dependent: Internal absolute paths prevent moving or copying the .venv.

• Domain Limited: Isolates Python packages only; underlying system libraries (e.g., CUDA, glibc) remain globally shared.

Lifecycle & Tooling Integration

State and Execution

• State Capture: Exact reproducibility requires cryptographic lockfiles (uv.lock), not loose pip freeze outputs.

• Version Control: .venv directories must be strictly excluded via .gitignore.

• Context Disconnect: Terminal activation alters $PATH but does not automatically link to Jupyter notebooks or IDEs.
