问题 It seems like ipywidgets.interactive tries to make every imput after the function to be a widget. In the following example, I get two widgets, one for age and one for name : import ipywidgets def greetings(age, name='John'): print(f'{name} is {age} years old') ipywidgets.interactive(greetings, age = widgets.IntSlider(), name = "Bob") My expectation was, that I only get one widget for age , since it is of type ipywidgets.widgets.widget_int.IntSlider whereas "Bob" is of type str (where I don't

问题 I'm trying to scroll through some magnetic resonance slices using plt.show() and ipywidgets interact() function. I've found no problem by slowly moving the slider, but an important delay is found when sliding through the slices a little bit faster. Here below is the code I'm using. def dicom_animation(x, volume): fig = plt.figure(figsize=(8,8)) plt.imshow(volume['slices'][x]['pixel_array'], cmap=plt.cm.gray) interact(dicom_animation, volume = fixed(a), x=IntSlider(round(len(a['slices'])/2,0),

I want to show some table style data. 回答1: This may be a brittle solution, but it seems to work. Add a html magic section giving the css styling: %%html <style> textarea, input { font-family: monospace; } </style> 回答2: This also works: from IPython.display import display from IPython.core.display import HTML display(HTML("<style>textarea, input { font-family: monospace;
