So I'm trying to create dropdown menu that loads different goes satellite data but when i embed the code to my code nothing displays but it displays perfectly on Notebook and yes i am using Visual studio code

import cartopy.crs as ccrs
import cartopy.feature as cfeature
from IPython.display import display
from ipywidgets import Dropdown, interact, fixed, Select
from matplotlib import patheffects
import matplotlib.pyplot as plt
import metpy
from metpy.plots import add_timestamp
import numpy as np
from siphon.catalog import TDSCatalog
def open_dataset(date, channel, idx, region):
    Open and return a netCDF Dataset object for a given date, channel, and image index
    of GOES-16 data from THREDDS test server.
    cat = TDSCatalog('https://thredds.ucar.edu/thredds/catalog/satellite/goes/east/products/'
    ds = cat.datasets[idx]
    ds = ds.remote_access(use_xarray=True)   
    return ds
def plot_GOES16_channel(date, idx, channel, region):
    Get and plot a GOES 16 data band from the ABI.
    ds = open_dataset(date, channel, idx, region)
    dat = ds.metpy.parse_cf('Sectorized_CMI')
    proj = dat.metpy.cartopy_crs
    x = dat['x']
    y = dat['y']

    fig = plt.figure(figsize=(10, 10))
    ax = fig.add_subplot(1, 1, 1, projection=proj)
    ax.add_feature(cfeature.COASTLINE, linewidth=2)
    ax.add_feature(cfeature.STATES, linestyle=':', edgecolor='black')
    ax.add_feature(cfeature.BORDERS, linewidth=2, edgecolor='black')

    for im in ax.images:
    im = ax.imshow(dat, extent=(x.min(), x.max(), y.min(), y.max()), origin='upper')
    timestamp = datetime.strptime(ds.start_date_time, '%Y%j%H%M%S')
    add_timestamp(ax, time=timestamp, high_contrast=True, 
                  pretext=f'GOES 16 Ch.{channel} - ',
                  time_format='%d %B %Y %H%MZ', y=0.01,
channel_list = {u'1 - Blue Band 0.47 \u03BCm': 1,
                u'2 - Red Band 0.64 \u03BCm': 2,

                u'5 - Snow/Ice Band 1.6 \u03BCm': 5,
                u'6 - Cloud Particle Size Band 2.2 \u03BCm': 6,
                u'7 - Shortwave Window Band 3.9 \u03BCm': 7,
                u'8 - Upper-Level Tropo. WV Band 6.2 \u03BCm': 8,
                u'9 - Mid-Level Tropo. WV Band 6.9 \u03BCm': 9,
                u'10 - Low-Level WV Band 7.3 \u03BCm': 10,
                u'11 - Cloud-Top Phase Band 8.4 \u03BCm': 11,
                u'12 - Ozone Band 9.6 \u03BCm': 12,
                u'13 - Clean IR Longwave Band 10.3 \u03BCm': 13,
                u'14 - IR Longwave Band 11.2 \u03BCm': 14,
                u'15 - Dirty Longwave Band 12.3 \u03BCm': 15,
                u'16 - CO2 Longwave IR 13.3 \u03BCm': 16}

region = Select(
    options=['Mesoscale-1', 'Mesoscale-2', 'CONUS', 'PuertoRico', 'FullDisk'],

channel = Dropdown(

date = datetime.utcnow()
interact(plot_GOES16_channel, date=fixed(date), idx=fixed(-2), 
         channel=channel, region=region)```

    $\begingroup$ Your question appears to be purely about programming (create dropdown menu in matplotlib) or hardware (not working on tkinter) and not about Earth Science. Perhaps you should ask your question on an appropriate Stack Exchange programming site. $\endgroup$
