Iterating Over Multiple Columns in a Pandas DataFrame: A Simple yet Effective Solution
The issue with your current implementation is that when iterating over two columns (in this case neighborhood_results['neighborhood'] and itself), the outer loop doesn’t have a clear way to keep track of which iteration it’s on. Here’s how you can do it using iterators: for i, (nei1, nei2) in enumerate(zip(neighborhood_results['neighborhood'], neighborhood_results['neighborhood'])): ratio = fw.partial_ratio(nei1, nei2) if ratio > 90: neighborhood_results.loc[i, 'neighborhood'] = neighborhood_results.loc[j, 'neighborhood'] Here’s how it works: We use the zip function to iterate over both columns at once (neighborhood_results['neighborhood'] and itself).
