Is there a way where you can reassign options to dropdown in ipywidgets

Question

I want to update the dropdown option when i update the referred list. Is there a way of doing it?

options_list = []

def update_options_list():
c.exexute('SQL CODES')
for ids in c:
  options_list.append(c[0])

dropdown_lable = widgets.Dropdown(options=options_list, value = None)

def button_function():
  update_options_list
  dropdown_lable.options = options_list

Is there a way to apply the updated options list to dropdown_lable.options?

I come across this error: 'NoneType' object is not callable

Answer 1

Simply

dropdown_lable.options = options_list

BTW:

Using Google ipywidgets dropdown update options I found it in 5 minutes.
And you had to wait 1 hour for answer on Stackoverflow. Next time first check in Google.

EDIT:

Minimal working example

import ipywidgets as widgets

# --- functions ---

def update_options(widget):
    global options
    
    #print('widget:', widget)
    #widget.description = 'Updated !!!'
    
    options = ['A', 'B', 'C']        
    dropdown.options = options
    
# --- main ---

options = [1, 2, 3]

dropdown = widgets.Dropdown(options=options)

button = widgets.Button(description='Update')
button.on_click(update_options)

box = widgets.HBox([dropdown, button])

box
