Key Concepts

Data Parsing and Cleaning

Once data is acquired from online sources, it often requires parsing to convert raw data into structured formats, such as lists or data frames. This concept also encompasses cleaning procedures to remove errors, inconsistencies, or irrelevant parts of the data, ensuring it is ready for analysis or further processing.

Online Data Acquisition

This concept involves retrieving data from internet sources. It covers techniques for connecting to remote servers, downloading raw data, and handling communication protocols (such as HTTP) to obtain the desired information.

API Interaction

APIs (Application Programming Interfaces) are critical for accessing online data in a structured and reliable manner. They allow programmers to request specific data and receive responses in standard formats like JSON or XML, facilitating easier integration and processing of online information.
