Code before:

                 slidermax=None, dragging=True, valstep=None,

        Parameters
        ----------
        ax : Axes
            The Axes to put the slider in.

        label : str
            Slider label.

        valmin : float
            The minimum value of the slider.

        valmax : float
            The maximum value of the slider.

        valinit : float, default: 0.5
            The slider initial position.

        valfmt : str, default: None
            %-format string used to format the slider value. If callable, will
            be called with the value as a single float argument, and should
            return a string. If None, a `.ScalarFormatter` is used instead.

        closedmin : bool, default: True
            Whether the slider interval is closed on the bottom.

        closedmax : bool, default: True
            Whether the slider interval is closed on the top.

        slidermin : Slider, default: None
            Do not allow the current slider to have a value less than
            the value of the Slider *slidermin*.

        slidermax : Slider, default: None
            Do not allow the current slider to have a value greater than
            the value of the Slider *slidermax*.

        dragging : bool, default: True
            If True the slider can be dragged by the mouse.

        valstep : float or array-like, default: None
            If a float, the slider will snap to multiples of *valstep*.
            If an array the slider will snap to the values in the array.

        orientation : {'horizontal', 'vertical'}, default: 'horizontal'
            The orientation of the slider.


Review comment (suggestion):
I think this wording as a bit more concise:
```suggestion
            The way to format the slider value. If a string, if must be in %-format.
            If a callable, it must have the signature ``valfmt(val: float) -> str``.
            If None, a `.ScalarFormatter` is used.
```

                 orientation='horizontal', initcolor='r',
