Getting Started Guide

To get started with the Pandas repository:

Install Pandas:

pip install pandas

Import Pandas and Read Data: Load Pandas into your Python environment and start reading data from various sources like CSV files, SQL databases, or Excel spreadsheets.

import pandas as pd

# Load data from a CSV file
df = pd.read_csv('data.csv')

Perform Data Manipulation: Use Pandas' rich API to filter, group, merge, and manipulate your data efficiently.

# Filter data
filtered_df = df[df['column'] > 100]

# Group and aggregate data
summary = df.groupby('category').sum()
