📘 What is Python?

Python is a high-level, interpreted programming language known for its readability, simplicity, and versatility, often used for web development, data analysis, artificial intelligence, and scientific computing.

🤔 Why am I learning Python?

• Python was my first programming language 👶, so I want to re-learn it and make a cheat sheet for future reference.
• I want to use 🦜 LangChain and ⚡️ FastAPI for my projects. 🚀
• I want to learn 🤖 Machine Learning. There are many libraries for that in Python.
