Course Description
Before you can analyze data, you first have to acquire it. This course teaches you how to build pipelines to import data kept in common storage formats. You’ll use pandas, a major Python library for analytics, to get data from a variety of sources, from spreadsheets of survey responses, to a database of public service requests, to an API for a popular review site. Along the way, you’ll learn how to fine-tune imports to get only what you need and to address issues like incorrect data types. Finally, you’ll assemble a custom dataset from a mix of sources.

Data scientist via spatial analytics and geography.
A geographer by training, Amany drifted into data science via spatial analytics. These days, they spend a lot of time thinking about how best to structure data and streamline acquisition processes for reporting and analytics, mostly for government agencies and nonprofits. They enjoy demystifying data science and coding concepts.
