[Python] adding on_click methods to buttons created with ipywidgets

I am using ipywidgets to create a dashboard.

I create a bunch of buttons using a loop:

from ipywidgets import GridspecLayout

grid = GridspecLayout(4, 3)
def create_expanded_button(description, button_style):
return Button(description=description, button_style=button_style, layout=Layout(height='auto', width='auto'))


for i in range(4):
for j in range(3):
grid[i, j] = create_expanded_button('Button {} - {}'.format(i, j), 'warning')
grid


This is the code in the documentation. With such a code you create a dashboard with 16 buttons:



The question is what is the strategy as to how to handle every on_click methods of the buttons since all the buttons are called the same. Do the buttons have a kind of 'id'?

imagine that by clicking every button I want to fetch a particular data online. how to proceed?

thanks.
