Pandas pivote multi índice

Uses unique values from specified index / columns to form axes of the resulting DataFrame. This function does not support data aggregation, multiple values will  

Keys to group by on the pivot table index. If an array is passed, foo one 4 1 two 0 6. The next example aggregates by taking the mean across multiple columns. Uses unique values from specified index / columns to form axes of the resulting DataFrame. This function does not support data aggregation, multiple values will   unstack : (inverse operation of stack ) “pivot” a level of the (possibly hierarchical) row index to the column axis, producing a reshaped DataFrame with a new inner-   Pivot a level of the (necessarily hierarchical) index labels.

We're able to set multiple row indexes on a pivot table the very same way we did earlier: by  Oct 2, 2017 Hierarchical indices, groupby and pandas. In this tutorial, you'll learn about multi- indices for pandas DataFrames and how they arise naturally  Pandas melt() function is used to change the DataFrame format from wide to long . Let's see what happens when we pass multiple columns as the id_vars The pivot() function 'index' parameter value should be same as the 'id_vars' value. If we ask to see these groups, we'll be able to see which indices in the original DataFrame correspond to each group. In [4]: The output of the mean methood is a regular ole pandas Series. We can also group a Series by multiple Series. Jan 3, 2016 Learn Pandas techniques like impute missing values, binning, pivot, Multi- index requires tuple for defining groups of indices in pandas loc 

You can group and then unstack. >>> df.groupby(['year', 'month', 'item'])['value']. sum().unstack('item') item item 1 item 2 year month 2004 1 33
