Agar version number dikhta hai (e.g., Python 3.12.2), to installation successful hai 🎉

Python IDEs (Code likhne ke tools)

IDE ka matlab hai Integrated Development Environment — jahan aap Python code likh, run, aur debug kar sakte ho.

• 🧠 VS Code — Lightweight aur powerful (recommended)
• 🐍 PyCharm — Advanced IDE for professional development
• 🧮 Jupyter Notebook — Best for data science aur ML projects
• 💻 IDLE — Python ke sath pre-installed simple editor

VS Code Install Karna

1️⃣ Download from VSCode website
2️⃣ Install Python extension by Microsoft (it adds syntax highlighting aur debugging support)
3️⃣ Create ek naya file hello.py aur likho:
