https://flypython.com/learn Practical, verified guides for Python foundations, web APIs, automation, and reliable AI agents. en Sun, 06 Sep 2026 00:00:00 GMT https://flypython.com/learn/t-strings-for-llm-prompts https://flypython.com/learn/t-strings-for-llm-prompts Python 3.14 template strings (PEP 750) give prompt construction what f-strings never had — a structured Template object with literal text and interpolated values held separately until you render them. Sun, 06 Sep 2026 00:00:00 GMT https://flypython.com/learn/agents-md-single-source https://flypython.com/learn/agents-md-single-source AGENTS.md is now a neutral standard under the Agentic AI Foundation. Use one repository file to define build, test, and change rules for Claude Code, Codex, Cursor, and every agent you adopt next. Sun, 06 Sep 2026 00:00:00 GMT https://flypython.com/learn/mcp-2026-07-28-migration https://flypython.com/learn/mcp-2026-07-28-migration The 2026-07-28 MCP specification removed the initialize handshake, replaced elicitation with an input_required round-trip, and deprecated roots, sampling, and logging. Here is the migration path for Python servers. Sun, 06 Sep 2026 00:00:00 GMT https://flypython.com/learn/uv-python-workflow https://flypython.com/learn/uv-python-workflow Move a Python project to uv with pinned interpreters, a lockfile, single-command runs, and inline script metadata — including the migration path from pip, venv, and Poetry. Sun, 06 Sep 2026 00:00:00 GMT https://flypython.com/learn/free-threaded-python-decision https://flypython.com/learn/free-threaded-python-decision Python 3.15 ships in October 2026 with a dedicated Stable ABI for free-threaded builds. Use this decision guide and a dual-build CI check to choose without guessing. Sun, 06 Sep 2026 00:00:00 GMT https://flypython.com/learn/ai-coding-context-budget https://flypython.com/learn/ai-coding-context-budget Maximize coding agent accuracy by controlling context size, writing explicit task contracts, and enforcing automated verification loops before human review. Wed, 02 Sep 2026 00:00:00 GMT https://flypython.com/learn/ai-coding-workflow https://flypython.com/learn/ai-coding-workflow A contract-first workflow for using coding agents to make small, testable, and safe Python changes — task contracts, repository inspection, reproducible environments, and evidence-based handoffs. Wed, 02 Sep 2026 00:00:00 GMT https://flypython.com/learn/reliable-async-patterns https://flypython.com/learn/reliable-async-patterns Build resilient concurrent Python applications by avoiding common async antipatterns — blocking IO in the event loop, unstructured gather, unbounded concurrency, and leaked resources. Wed, 02 Sep 2026 00:00:00 GMT https://flypython.com/learn/modern-python-typing https://flypython.com/learn/modern-python-typing Use Protocol, TypedDict, PEP 695 generics, and static type checking as machine-enforced contracts that constrain AI-generated code and catch regressions before execution. Wed, 02 Sep 2026 00:00:00 GMT https://flypython.com/learn/python-product-quality https://flypython.com/learn/python-product-quality A practical quality model for moving from a useful script to an operable Python product with explicit boundaries, tested failure paths, and reversible releases. Wed, 02 Sep 2026 00:00:00 GMT https://flypython.com/learn/safe-retryable-python-automation https://flypython.com/learn/safe-retryable-python-automation Design a repeated task as an observable Python workflow with explicit inputs, idempotent writes, bounded retries, checkpoints, and recovery evidence. Mon, 31 Aug 2026 00:00:00 GMT https://flypython.com/learn/python-web-api-boundaries https://flypython.com/learn/python-web-api-boundaries Plan a Python API around validated input, stable responses, timeouts, observable failures, and a deployment contract before choosing more infrastructure. Mon, 31 Aug 2026 00:00:00 GMT https://flypython.com/learn/python-foundations-with-tests https://flypython.com/learn/python-foundations-with-tests Learn a repeatable Python project loop built around isolated environments, explicit data contracts, failure cases, and standard-library tests. Mon, 31 Aug 2026 00:00:00 GMT https://flypython.com/learn/python-ai-agent-roadmap https://flypython.com/learn/python-ai-agent-roadmap Build a small troubleshooting agent with bounded tools, validated actions, an ordered action-name trace, and automated tests using only the Python standard library.
