ignore_index bool, default False. If True, the resulting index will be labeled 0, 1, , n – 1. Returns: DataFrame. Exploded lists to rows of the subset columns; index will be duplicated for these rows.

Notes. The aggregation operations are always performed over an axis, either the index (default) or the column axis. This behavior is different from numpy aggregation functions (mean,

Missing data / operations with fill values#. In Series and DataFrame, the arithmetic functions have the option of inputting a fill_value, namely a value to substitute when at most one of the values

Indexing is similar to pandas, but more explicit and leverages xarray’s naming of dimensions. Because of those features, making much higher dimensional data is very practical.

One Dask DataFrame is comprised of many in-memory pandas DataFrame s separated along the index. One operation on a Dask DataFrame triggers many pandas operations on the

In the past, pandas recommended Series.values or DataFrame.values for extracting the data from a Series or DataFrame. You’ll still find references to these in old code bases and online. Going
