Question

BlackTom AI · Accepted Answer

Pandas operations on Series often involve alignment by index, which means the arithmetic is performed by matching labels rather than positions. 
Option 1: True. This statement is correct because when you add, subtract, multiply, or divide two Series, pandas aligns them on their index labels; values with the same index label are combined, while non-overlapping labels yield NaN in the result. This automatic reindexing behavior is a key feature that supports intuitive operations on labeled data. 
Option 2: False. This would be incorrect because the default behavior is not to perform purely position-based arithmetic; it explicitly aligns by index. If you expected it to ignore indices and rely on order, you would be surprised by NaN results where indices don't match, which contradicts the actual behavior. 
In summary, the automatic index alignment in Series arithmetic is intentional and fundamental to how pandas handles labeled data, producing NaN where labels differ between operands.
