Which technologies and frameworks should a new Python team adopt first?

The technologies a new Python team should adopt first are FastAPI or Django, PostgreSQL with SQLAlchemy, pytest, Black/Ruff/mypy, poetry or pip‑tools, Docker, GitHub Actions, Terraform, and a major cloud.

1. Application framework baseline

• FastAPI or Django anchors routing, validation, and auth patterns. Consistency accelerates feature delivery and onboarding.
• Templated service repos enforce structure and security defaults. Typed Pydantic models improve reliability across endpoints.

2. Data layer and storage

• PostgreSQL with SQLAlchemy or Django ORM offers robust transactions. Migrations control schema evolution safely.
• Sensible indexing and connection pooling protect latency. Backups and PITR policies safeguard critical data.

3. Testing and code quality

• pytest with coverage enforces correctness at unit and integration levels. Black, Ruff, and mypy standardize readability and safety.
• Contract tests pin API behavior for clients. Pre‑commit hooks block issues before CI.

4. Packaging and environments

• poetry or pip‑tools reproducibly lock dependencies. Versioning and changelogs clarify upgrade impacts.
• Docker images encapsulate runtime parity across envs. Multi‑stage builds trim size and speed deployments.

5. CI/CD and cloud foundation

• GitHub Actions pipelines run tests, scans, and deploy steps. Policy checks guard secrets and infrastructure drift.
• Terraform provisions VPC, databases, and IAM. A single cloud (AWS, GCP, or Azure) limits surface area early.
