Free AI Prompt Library - ChatGPT, Claude, Gemini

ChatGPT Prompt for Generating Python Code

ChatGPT has become an indispensable tool for Python developers, whether beginners or experienced. Thanks to its advanced understanding of natural language, it can transform a functional description into clean, structured, and functional Python code in seconds. But the quality of the generated code depends directly on the quality of the prompt used. A vague prompt will produce generic and often unusable code, while a well-structured prompt will generate production-ready code with error handling, typing, and documentation. In this guide, we provide optimized prompts to get the most out of ChatGPT for generating Python code. Whether you need to write an automation script, a REST API, a data processing algorithm, or a complex class, these prompts will help you obtain precise and professional results. The goal is to save you time while maintaining a high level of quality, guiding ChatGPT with the right instructions so that it respects PEP 8 conventions, includes docstrings, and produces maintainable code.

Gemini Prompt to Create E2E Tests

End-to-end (E2E) tests are essential to guarantee an application's overall correct functioning, yet writing them is often time-consuming and repetitive. Gemini, Google's AI model, excels at generating structured code and can dramatically accelerate the creation of complete E2E test suites. By providing the technical context of your application — tech stack, critical user journeys, and the test framework used — Gemini can produce robust test scenarios covering both main flows and edge cases. Whether you use Playwright, Cypress, or Selenium, the AI adapts to your framework's conventions to generate directly usable code. The prompt engineering approach allows you to precisely specify the desired coverage level, the selector patterns to favor, and the test data management strategy. The result: maintainable, readable tests aligned with your team's best practices, produced in a fraction of the usual time.

Prompt Claude for Generating a Database Schema

Designing a database schema is a fundamental step in any software project. A well-thought-out schema ensures data consistency, facilitates queries, and avoids long-term performance issues. Yet, this task requires expertise in relational modeling, normalization, and choosing data types suited to the target DBMS. Claude excels in this area: by providing a functional description of your project, it generates a complete schema with tables, columns, types, constraints, indexes, and relationships. It applies best practices for normalization, suggests consistent naming conventions, and anticipates common needs like audit columns or soft deletes. Whether you start from a specification, a list of business entities, or an existing schema to refactor, Claude produces a DDL ready to execute or a structured diagram that you can iteratively refine. This is a valuable accelerator for solo developers and teams alike who want to quickly validate a data architecture before coding.
