Speeding Up Python Applied Row-Wise Functions Overview When working with pandas DataFrames, it’s common to apply row-wise functions to clean or transform data. However, these operations can be computationally expensive and slow when applied individually to each row using the apply method. In this article, we’ll explore ways to optimize these operations and provide examples of vectorized methods that can significantly improve performance. Why apply is Slow The main issue with using apply on a full DataFrame is that it creates a new Series for each row in the DataFrame and sends that to the function passed to apply.
