Pandas Data Analysis

pluginagentmarketplace/custom-plugin-python

This is a foundational skill for anyone doing data work with Claude Code. It covers the bread and butter of pandas: loading data from CSVs, Excel, SQL, and APIs, then cleaning and transforming it into something usable. The learning objectives hit exploratory analysis, grouping and aggregation, plus visualization and performance optimization for larger datasets. It's practical stuff you'll reach for constantly if you're wrangling messy data or building analysis workflows. The skill comes from pluginagentmarketplace's custom Python plugin collection and has passed security audits from Gen Agent Trust Hub, Socket, and Snyk, so it's vetted for production use.

Pandas Data Analysis

Overview

Master data analysis with Pandas, the powerful Python library for data manipulation and analysis. Learn to clean, transform, analyze, and visualize data effectively.

Learning Objectives

Load and manipulate data from various sources (CSV, Excel, SQL, APIs)
Clean and transform messy datasets
Perform exploratory data analysis (EDA)
Aggregate and group data for insights
Create compelling visualizations
Optimize performance for large datasets

Core Topics

1. Pandas DataFrames & Series

Creating DataFrames from various sources
Indexing and selecting data (loc, iloc, at, iat)
Filtering and boolean indexing
Adding/removing columns and rows
Data types and conversions

Code Example:

import pandas as pd
import numpy as np

# Create DataFrame
data = {
    'name': ['Alice', 'Bob', 'Charlie', 'David'],
    'age': [25, 30, 35, 28],
    'salary': [50000, 60000, 75000, 55000],
    'department': ['IT', 'HR', 'IT', 'Sales']
}
df = pd.DataFrame(data)

# Indexing and filtering
it_employees = df[df['department'] == 'IT']
high_earners = df.loc[df['salary'] > 55000, ['name', 'salary']]
