Before we can analyze data, we need to collect it from reliable sources. In the real world, data is rarely handed to us in a clean and structured format. Instead, we have to gather it from various sources such as APIs, web scraping, and databases. Each method has its own advantages and use cases, and understanding when to use each is an essential skill for a data scientist.
