Begin your journey into Data Science! Even if you've never written a line of code in your life, you'll be able to follow this course and witness the power of Python to perform Data Science. You'll use data to solve the mystery of Bayes, the kidnapped Golden Retriever, and along the way you'll become familiar with basic Python syntax and popular Data Science modules like Matplotlib (for charts and graphs) and pandas (for tabular data).
Getting Started in PythonFree
Welcome to the wonderful world of Data Analysis in Python! In this chapter, you'll learn the basics of Python syntax, load your first Python modules, and use functions to get a suspect list for the kidnapping of Bayes, DataCamp's prize-winning Golden Retriever.Dive into Python50 xpImporting Python modules100 xpCorrecting a broken import100 xpCreating variables50 xpCreating a float100 xpCreating strings100 xpCorrecting string errors100 xpValid variable names50 xpFun with functions50 xpLoad a DataFrame100 xpCorrecting a function error100 xpSnooping for suspects100 xp
Loading Data in pandas
In this chapter, you'll learn a powerful Python libary: pandas. pandas lets you read, modify, and search tabular datasets (like spreadsheets and database tables). You'll examine credit card records for the suspects and see if any of them made suspicious purchases.What is pandas?50 xpLoading a DataFrame100 xpInspecting a DataFrame100 xpSelecting columns50 xpTwo methods for selecting columns100 xpCorrecting column selection errors100 xpMore column selection mistakes100 xpSelecting rows with logic50 xpLogical testing100 xpSelecting missing puppies100 xpNarrowing the list of suspects100 xp
Plotting Data with Matplotlib
Get ready to visualize your data! You'll create line plots with another Python module: Matplotlib. Using line plots, you'll analyze the letter frequencies from the ransom note and several handwriting samples to determine the kidnapper.
Different Types of Plots
In this final chapter, you'll learn how to create three new plot types: scatter plots, bar plots, and histograms. You'll use these tools to locate where the kidnapper is hiding and rescue Bayes, the Golden Retriever.

What do other learners have to say?
I've used other sites—Coursera, Udacity, things like that—but DataCamp's been the one that I've stuck with.
