Скачать или смотреть Python .iloc Tutorial with Seaborn Iris Dataset | Slice Data & Calculate Means Easily

Master the `.iloc` indexer in Python with this beginner-friendly tutorial using Seaborn’s famous Iris dataset! We’ll load the Iris dataset with `seaborn`, then use `.iloc` to slice rows and columns—like grabbing the first row’s first column or all rows for the first three columns. Plus, we’ll calculate the average sepal length in one line of code! Perfect for data analysis beginners, Python learners, or anyone exploring pandas and Seaborn for real-world data tasks.

🔍 *What You'll Learn:*
Loading datasets with Seaborn (`sns.load_dataset`)
Using `.iloc` to slice rows and columns by index
Calculating means with `.mean()` on sliced data
Understanding Iris dataset structure

💻 *Code Used in This Video:*
import seaborn as sns
iris = sns.load_dataset('iris')

Slice with .iloc [rows, columns]
print(iris.iloc[0:1, 0:1]) # First row, first column
print(iris.iloc[:, 0:3]) # All rows, first 3 columns

Average sepal length in one line
print(iris.iloc[:, 0].mean()) # Output: 5.84333...

🌟 *Why Learn .iloc?*
The `.iloc` indexer is a pandas powerhouse for data slicing—essential for data science, machine learning, and analytics. Using the Iris dataset, we’ll show you how to extract specific data (e.g., sepal length) and compute stats like averages, all while explaining each step. Whether you’re prepping for a data job or just love Python, this tutorial makes data manipulation simple and fun!

📚 *Who’s This For?*
