Pandas: None Vs NaN In Python? (Explained) - Python Code School
Pandas: None Vs NaN In Python? (Explained) Are you working with data in Python and wondering how to properly handle missing values? In this informative video, we'll explain the differences between None and NaN in pandas, a popular library for data analysis. We'll start by defining what None and NaN are, and how they are used in Python and pandas to represent missing or undefined data. You'll learn how None acts as a general placeholder for no value, especially in object columns containing strings or mixed data types. We'll also explore how NaN is used specifically for missing numerical data, and why it is the default marker for such cases in pandas and NumPy. Additionally, we'll introduce pd.NA, a newer missing value indicator designed to work across different data types for more consistent data handling. Understanding when to use None, NaN, or pd.NA can greatly improve your data cleaning process and ensure your calculations behave as expected. Whether you're analyzing datasets or preparing data for machine learning, recognizing these differences helps you manage missing data more effectively.
