apply
Apply a function column-wise, row-wise, or table-wise.
Updates the HTML representation with the result.
func should take a Series or DataFrame (depending on axis), and return an object with the same shape. Must return a DataFrame with identical index and column labels when axis=None.
func
axis
axis=None
Apply to each column (axis=0 or 'index'), to each row (axis=1 or 'columns'), or to the entire DataFrame at once with axis=None.
axis=0
'index'
axis=1
'columns'
A valid indexer to limit data to before applying the function. Consider using a pandas.IndexSlice.
data
Pass along to func.
Notes
The output shape of func should match the input, i.e. if x is the input row, column, or table (depending on axis), then func(x).shape == x.shape should be true.
x
func(x).shape == x.shape
This is similar to DataFrame.apply, except that axis=None applies the function to the entire DataFrame at once, rather than column-wise or row-wise.
DataFrame.apply
Examples
>>> def highlight_max(x): ... return ['background-color: yellow' if v == x.max() else '' for v in x] ... >>> df = pd.DataFrame(np.random.randn(5, 2)) >>> df.style.apply(highlight_max)
