pandas.DataFrame¶ class pandas.DataFrame (data=None, index=None, columns=None, dtype=None, copy=False) [source] ¶ Two-dimensional size-mutable, potentially heterogeneous tabular data structure with labeled axes (rows and columns). Arithmetic operations align on both row and column labels. Can be thought of as a dict-like container for Series python - Boolean mask for Pandas DataFrame columns - This is because Pandas uses treats boolean slices as masks, but integer slices as lookups. In your example, you can see that columns[[1, 0, 1]] looks up the second second column, then the first, then the second columns:["b", "a", "b"]. To convert your integer indexes into booleans, you can use either: sklearn.datasets.load_diabetes scikit-learn 0.24.1 The target is a pandas DataFrame or Series depending on the number of target columns. If return_X_y is True, then (data, target) will be pandas DataFrames or Series as described below. New in version 0.23. Returns data Bunch. Dictionary-like object, with the following attributes.

The mask method is an application of the if-then idiom. For each element in the calling DataFrame, if cond is False the element is used; otherwise the corresponding element from the DataFrame other is used.. The signature for DataFrame.where() differs from numpy.where().Roughly df1.where(m, df2) is equivalent to np.where(m, df1, df2).. For further details and examples see the
