One-Hot Encoding in Python: Why for Loops Fail When Updating Original DataFrames
Onehotencoded DataFrame Won’t Join with Original DataFrame in For Loop Introduction In this article, we will explore a common pitfall when working with One-Hot Encoding (OHE) in Python. Specifically, we will investigate why the assignment of an OHE-encoded DataFrame to the original DataFrame does not work as expected when used within a for loop. Background One-Hot Encoding is a technique used to transform categorical variables into numerical representations that can be processed by machine learning algorithms.
