Is there any solution to make work downloading process and tkinter gui at same time

Here's the translated code for the provided Python code. I've excluded the code comments:

try:

ftp.login(user=user_id, passwd=psswd)
dir_names = ftp.nlst()
print('connecting to server')
if not os.path.isdir(os.getcwd() + '/output'):
os.mkdir(os.getcwd() + '/output')
output_dir_name = self.make_date_dir()
for s in sniffers_list:
print(f'searching for sniffer "{s}"')
self.gui.change_lbl()

date_file = datetime.strptime(string1, '%d.%m.%y %H:%M')
if date_start <= date_file <= date_end:
is_date_found = True
print(f'downloading file {file}')
path = os.getcwd() + '/dir_output' + '/' + output_dir_name + '/' + 'S' + s.strip('sni')

And a simple GUI:

super().__init__()
self.lbl_download = customtkinter.CTkLabel(master=self, font=("Helvetica", 16), text="")

self.title("StaMes GUI")
self.snidatadl = snidatadl
self.date_start = date_start
self.date_end = date_end
self.sniffers_list = sniffers_list
self.create_widgets()
def create_widgets(self):
# DATE FROM
decotarion1_label = customtkinter.CTkLabel(master=self, text="FROM: ", font=("Helvetica", 16))
decotarion1_label.place(x=100, y=50)
date1_label = customtkinter.CTkLabel(master=self, text=self.date_start)
date1_label.place(x=160, y=50)
# DATE TO
decotarion2_label = customtkinter.CTkLabel(master=self, text="TO: ", font=("Helvetica", 16))
decotarion2_label.place(x=350, y=50)
date2_label = customtkinter.CTkLabel(master=self, text=self.date_end)
date2_label.place(x=380, y=50)
# TABLE SNIFFERS
scrollable_frame = customtkinter.CTkScrollableFrame(master=self, width=400, height=300)
scrollable_frame.place(x=80, y=100)
i = 0
for x in self.sniffers_list:
print(x)
name = customtkinter.CTkLabel(master=scrollable_frame, text=x)
name.grid(row=i, column=0, padx=20)
i = i + 1
# BUTTON
run_btn = customtkinter.CTkButton(master=self, text="RUN", command=lambda: self.run())
run_btn.place(x=350, y=420)
# LABEL
self.lbl_download.place(x=100, y=420)
def run(self):
threading.Thread(target= self.snidatadl.download_sniffers_data(self.date_start, self.date_end, self.sniffers_list, self))
def change_lbl(self):
self.lbl_download.configure(text="DOWNLOADING...")
The idea, is to click on the button "RUN" and call the fuction to download some info, but I need to update the GUI while is running the download.
I have already try the asyncio, and i read about threading, which you think it could be the better idea to fix it?
I already try it with a minimal reproducible project, but still not working.

我用一句话修复了它。
在调用change_lbl()方法之后添加self.gui.update()。
英文:
I fixed it with 1 sentence.
Adding
self.gui.update()
after calling the method change_lbl()
