如何在ipywidgets Interact功能上删除/更改小部件的标签？

Question

In the following example:

from ipywidgets import interact
import numpy as np

from bokeh.models import Slider

from bokeh.io import push_notebook, show, output_notebook
from bokeh.plotting import figure
output_notebook()

x = np.linspace(0, 2*np.pi, 2000)
y = np.sin(x)

p = figure(title="simple line example", plot_height=300, plot_width=600, y_range=(-5,5))
r = p.line(x, y, color="#2222aa", line_width=3)




def update(f, w=1, A=1, phi=0):
    f.title='fdsafdsafewa'
    if   f == "sin": func = np.sin
    elif f == "cos": func = np.cos
    elif f == "tan": func = np.tan
    r.data_source.data['y'] = A * func(w * x + phi)
    push_notebook()

show(p, notebook_handle=True)


interact(update, f='Hi there!', w=(1,5), phi=(0, 20, 0.1))

The graph produced is as follows:

Currently, the variables w, a and phi assigned to the sliders show up to the left of the slider as labels. Is there a way to remove them, or change the labels in a manner which doesn't involve editing their variable names in the interact section?

Answer 1

First off, interact is not part of Bokeh at all, it is part of the ipywidgets library. In any case the labels are taken from the function parameter names, so you only need to change them however you like, eg

interact(update, Omega=1, Amplitude=1, Phase=0):
