| 11 | 🧮 Why does NumPy let you add a number to an entire matrix?
Look at this:
import numpy as np
x = np.array([
[10, 20, 30],
[40, 50, 60]
])
x + 5
You get:
[[15, 25, 35],
[45, 55, 65]]
But where did the 5 go? You didn't write a loop. You didn't copy 5 six times.
This is broadcasting.
NumPy automatically treats the smaller object as if it were expanded to match the larger array's shape.
So conceptually:
[[10, 20, 30], [[5, 5, 5],
[40, 50, 60]] + [5, 5, 5]]
Then it adds them element by element.
And it works with arrays too:
x + np.array([1, 2, 3])
Conceptually:
[[10, 20, 30], [[1, 2, 3],
[40, 50, 60]] + [1, 2, 3]]
Result:
[[11, 22, 33],
[41, 52, 63]]
The important part:
Broadcasting doesn't literally copy the data into a bigger array.
NumPy applies the operation as if the smaller array had been expanded, while avoiding unnecessary copies.
That's why this:
x + 5
can work even though x is 2D and 5 is just a scalar. | 1 229 |

| 15 | 🧮 NumPy: Why axis=0 and axis=1 Feel Backwards
You've probably seen:
np.mean(X, axis=0)
and wondered:
"Why does axis 0 mean columns?"
Think about what NumPy is doing.
📌 axis=0 means:
Collapse the rows.
So you move down each column and get one value per column.
📌 axis=1 means:
Collapse the columns.
So you move across each row and get one value per row.
For:
1 2 3
4 5 6
np.mean(X, axis=0)
gives:
[2.5, 3.5, 4.5]
On the other hand:
np.mean(X, axis=1)
gives:
[2, 5]
Don't memorize the numbers.
Just Remember: The axis you specify is the dimension that gets collapsed.

Pandas is one of the most important tools for data analysis. Master these core operations to work faster and more efficiently:
🔹 Read & Inspect Data
head(), shape, dtypes, describe()
🔹 Select & Filter Data
Extract relevant rows and columns with ease.
🔹 Row Selection
Use loc[] (labels) and iloc[] (positions).
🔹 Handle Missing Values
isnull(), dropna(), fillna()
🔹 Group & Aggregate
Summarize data using groupby() and aggregation functions.
🔹 Merge & Join Data
Combine datasets with merge() using different join types.
