🐍 Python Day 2 – Variables & Data Types

Ninna manam Python install chesi first program run chesam.
Eroju manam Variables & Data Types nerchukundam.

👉 Variables ante data ni store cheyadaniki use chestam
👉 Data Types ante aa data type enti ani chepthayi

💡 Simple ga:
Variable = box 📦
Value = danilo unna item

Example:
box lo apple unte → variable lo value untundi 🍎

📦 Variables in Python

👉 Variable create cheyadam easy:

🎯 Mini Practice

name = "YourName"

age = 20

course = "Python"

print("Name:", name)

print("Age:", age)

print("Course:", course)

---
