Python Memory Explained in One Video | Variables, Memory Allocation, & Garbage Collection
Welcome back to **Pharma Coder**! 🚀
In this lecture, you'll understand one of the **most important concepts in Python Programming**—**Python Memory Management**.
Many beginners know how to write Python code but don't understand *what actually happens inside the computer* when a variable is created.
In this lecture, we'll visualize how Python stores data in memory, how variables reference objects, why some objects share memory, and how Python automatically frees unused memory using Garbage Collection.
This lecture is explained using **simple real-life analogies**, **memory diagrams**, **live coding**, and **interview-focused examples**, making it perfect for beginners and Pharma IT aspirants.

🔥 *Interview Question + Homework*
Without running the code, predict the output:
```python
a = 10
b = a
print(id(a))
print(id(b))
```
❓ Will both `id()` values be the same or different?
👇 Write your answer in the comments *and explain WHY.*
⭐ Bonus Challenge:
```python
x = [10, 20]
y = x
y.append(30)
print(x)
print(y)
```
Why did *both lists change?*
Let's see who gives the best explanation! 🚀
