Da Pandas Intro in Data Analytics

Pandas is Python's most important data analytics library. It provides the DataFrame — a 2D table structure similar to Excel or a database table — that makes working with structured data fast and intuitive.

A DataFrame has rows (records) and columns (features). Each column is a Series (a 1D array with labels). Together, they let you do in one line what would take 50 lines in pure Python.

Key Pandas operations: Read data (read_csv, read_excel), View data (head, tail, info, describe), Select (df['col'], df[df['col'] > value]), Filter (query), Group (groupby), Aggregate (mean, sum, count), Join (merge), Export (to_csv, to_excel).

Pandas is used in every data analytics job in India and worldwide. Learning Pandas is the single most important step for anyone interested in data science, data engineering, or business analytics.

# Note: In real code, first: pip install pandas
import pandas as pd

# Create DataFrame
df = pd.DataFrame({'name': ['Arjun', 'Priya'], 'marks': [85, 72]})

# Basic operations:
df.head()              # first 5 rows
df['marks'].mean()     # average marks
df[df['marks'] > 80]   # filter rows
df.groupby
