Moving forward, only labels (the first parameter) can be positional. just compare the code, you see what you've done wrong :-) (As I wrote, you just selected the columns which should be edited with, New!

Python pandas pivot table doesn't return all columns, Empty pivot table with pandas data frames.

Algebraically why must a single square root be done on all terms rather than individually? Here's a table contrasting the behaviors using the examples @jbrockmendel listed between 1.2.5 and 1.3.2, and master: With the fix in #43154 , we now have restored the 1.2.x behavior in the case of sum .
