What Is NaN In Python Pandas? Ever wondered how missing data is handled in Python data analysis? In this video, we'll explain everything you need to know about NaN in pandas. We'll start by defining what NaN stands for and how it is used to represent missing or undefined data in datasets. You'll learn how pandas detects these gaps using functions like isnull() and isna(), and how to count missing values with simple methods like sum(). We’ll also cover practical techniques for managing NaN, including replacing them with specific values using fillna(), or removing incomplete rows or columns with dropna(). Understanding the difference between NaN, zero, and empty strings is essential for accurate data processing. We’ll show you how NaN behaves during calculations, such as adding or dividing, and why proper handling of missing data is vital for your analysis or machine learning projects. This video provides practical tips for keeping your data clean and your results reliable. Whether you're cleaning datasets, filling gaps, or filtering out missing entries, mastering NaN management is a key part of working efficiently with pandas in Python.
