What You Will Learn


Data Wrangling

Knowing how to “wrangle data” (aka write code that cleans up “dirty” data and shapes it into useful formats) is a universally sought-after skill across data-driven companies. In this course you’ll learn how to leverage the power of Python to quickly gather, assess & clean messy data so it can be explored and analyzed easily.

In this course you’ll learn how to leverage the power of Python to quickly gather, assess & clean messy data so it can be explored and analyzed easily.

Prerequisite Knowledge

Python & SQL.

  • Intro to Data Wrangling

    Identify each step of the data wrangling process (gathering assessing, and cleaning) and wrangle a CSV file downloaded from Kaggle using fundamental gathering, assessing and cleaning code.

  • Gathering Data

    Gather data from multiple sources, including gathering files, programmatically downloading files, web-scraping data and accessing data from APIs.

  • Assessing Data

    Assess data visually and programmatically using pandas and identify data quality issues and categorize them using metrics: validity, accuracy, completeness, consistency and uniformity.

  • Cleaning Data

    Identify each step of the data cleaning process (defining, coding and testing) and clean data using Python and Pandas.

  • Course Project: Wrangle and Analyze Data

    Real-world data rarely comes clean. Using Python, you’ll gather data from a variety of sources, assess its quality and tidiness, then clean it. You’ll document your wrangling efforts in a Jupyter Notebook, plus showcase them through analyses and visualizations using Python and SQL.
