[Python] Python Script/Programm to Search & Display an Image from Local Folder

I'm an absolute beginner in python and trying to build a script/programm that searches images from a folder by their name (meaning that it would need a search bar) and displays these image in the same window.

Think of it as sort of a phonebook where I have stored 100 names and pictures and I want to type in "Henry" to see Henry's picture.

On my search for a software that achieves this, I've come accross something similar:

# img_viewer.py

import PySimpleGUI as sg
import os.path

# First the window layout in 2 columns

file_list_column = [
[
sg.Text("Image Folder"),
sg.In(size=(25, 1), enable_events=True, key="-FOLDER-"),
sg.FolderBrowse(),
],
[
sg.Listbox(
values=[], enable_events=True, size=(40, 20), key="-FILE LIST-"
)
],
]

# For now will only show the name of the file that was chosen
image_viewer_column = [
[sg.Text("Choose an image from list on left:")],
[sg.Text(size=(40, 1), key="-TOUT-")],
[sg.Image(key="-IMAGE-")],
]

# ----- Full layout -----
layout = [
[
sg.Column(file_list_column),
sg.VSeperator(),
sg.Column(image_viewer_column),
]
]

window = sg.Window("Image Viewer", layout)

# Run the Event Loop
while True:
event, values = window.read()
if event == "Exit" or event == sg.WIN_CLOSED:
break
# Folder name was filled in, make a list of files in the folder
if event == "-FOLDER-":
folder = values["-FOLDER-"]
try:
# Get list of files in folder
file_list = os.listdir(folder)
except:
file_list = []

fnames = [
f
for f in file_list
if os.path.isfile(os.path.join(folder, f))
and f.lower().endswith((".png", ".gif"))
]
window["-FILE LIST-"].update(fnames)
elif event == "-FILE LIST-": # A file was chosen from the listbox
try:
filename = os.path.join(
values["-FOLDER-"], values["-FILE LIST-"][0]
)
window["-TOUT-"].update(filename)
window["-IMAGE-"].update(filename=filename)

except:
pass

window.close()


This is almost perfect, but I would need to implement a search bar instead of clicking through the names as I will have ~20.000 entries and clicking through them is just not viable.

Any idea how I would go about achieving this?
