DataFrame Selection and Filtering

In this lesson, we will learn how to select columns and rows in a Pandas DataFrame, use loc and iloc, filter data based on conditions, and apply multiple conditions together. ## Lesson objective In this lesson, we will learn selection and filtering operations in a Pandas DataFrame. In the previous lesson, we learned how to read CSV, Excel, and JSON files with Pandas. After reading a file, the data comes into the Python environment as a DataFrame. However, reading data is only the beginning. In real analysis, we usually do not look at the entire dataset at once. Very often, we need specific columns, specific rows, or data that matches certain conditions.
