FastAPI Tutorial #4 | Path Parameters + Dynamic Routes + Validation

In this video, you will learn how to create dynamic routes using path parameters in FastAPI. We will understand how to pass values in URLs, use different data types like int and str, and apply basic validation. This concept is very important for building real-world APIs. Topics covered in this video: --What are path parameters --Create dynamic routes in FastAPI --Pass values through URL --Use data types (int, str) --Automatic validation in FastAPI --Error handling for invalid data --Path parameter examples --How FastAPI validates input --Common mistakes beginners make This video is useful for backend beginners, Python developers, and anyone learning API development. ⚙️ Tech Used and Code: Python, FastAPI, VS Code, Terminal 👉 *GitHub Code Link* - https://github.com/mohitdjcet/fastAPI-Tutorial 📂 *Playlist Links:* - Python Full Course Video (Hindi): https://www.youtube.com/playlist?list=PLsjpRo2EZP1Ja-GuGvkiPqmE3RGYP4lnI - DSA Full Tutorial: https://www.youtube.com/playlist?list=PLsjpRo2EZP1LKQePmuWv8jppLddppmGkn - Django Full Course Video (Hindi): https://www.youtube.com/playlist?list=PLsjpRo2EZP1K_glKX0lG6BkviJFxjuGls - Git and GitHib Copilot Full Course Video (Hindi): https://youtu.be/hebwERejgI4 - JavaScript Full Course Video (Hindi): https://youtu.be/moRFcW7xayc - HTML Crash Course : https://youtu.be/Zb_-6SttO3M - CSS Crash Course : https://youtu.be/b7PlBCjAJco 🔗 *Follow Me for Updates:* - TopMate:[Connect with Me](https://topmate.io/mohitdecodes) - WhatsApp:[Connect with Me](https://whatsapp.com/channel/0029Vb6CABUIHphQqGRYP71u) - Instagram: [Connect with Me](https://www.instagram.com/mohitdecodes/) - Facebook: [Connect with Me](https://www.facebook.com/mohitdecode/) - LinkedIn: [Connect with Me](https://www.linkedin.com/in/mohitdecodes/) - GitHub: [Explore My Projects](https://github.com/mohitdjcet/) fastapi path parameters fastapi dynamic routes fastapi tutorial beginners fastapi int str validation fastapi url parameters fastapi validation tutorial python fastapi routing fastapi examples fastapi error handling #fastapi #python #backenddevelopment #webdevelopment #apis #learnfastapi #coding #fastapipathparams #pythontutorial #mohitdecodes --- Copyright Notice: © Mohit Decodes.
