How to use input/command from selected button tkinter python

This may be tricky but I’ll try to put it clear. i have created two buttons, 1st button search folder and select individual filename as input, 2nd button select folder and take its directory as input and read all its files inside.

I want to create 3rd button(Execute) where it should know which button i selected and based on that it needs to do execute function.

Now,

import cx_oracle
conn = cx_oracle.connect()

from tkinter import*
from tinter import filedialog as fd
import pandas as pd
from tkinter import messagebox
from tkinter.messagebox import showinfo

window=Tk()
window.withdraw
window.title("ETL Automation")
winow.geometry("400x250+10+10")
window['bacground']='#34495E'

cursor = conn.cursor
global filename

def select_folder()
    folder_selected = filedialog.askdirectory()
    
def select_individual_file()
    filetypes = (
        'text files','*sql'),
        ('All files', '*.*')
    )
    global filename
    filename = fd.askopenfilename(title= ' ',
        initiadir=r'C:UsersDocuments',
        filetypes=filetypes)

#Now i wrote this for to execute 1 sql file         
def execute_query
    with open(filename) as inserts:
        query = inserts.read()
    cursor.execute(query)
    global row
    row = cursor.fetchall()
    messagebox.showinfo('Alert',"Query executed")
    

#This code to execute the sql files inside the folder_selected
cd = (folder_selected)

for root, dirnames, filenames in os.walk(folder_selected)
    for filenamess in fnmatch.filter(filnames, '*sql'):
    with open (cd+'\'+filenamess) as inserts:
    queries = inserts.read()
    cursor.execute(queries)
    rows = cursor.fetchall()
    
    
btn = Button(window, text="Select in Batch", fg = 'black',command=folder_selected,font="10")
btn = Button(window, text="Select single file", fg = 'black',command=select_individual_file,font="10")
btn = Button(window, text="Execute", fg = 'black',command=execute_query,font="10")

btn.place(x=40, y=80)
btn1.place(x=40,y=80)
btn1.place(x=40,y=80)
window.mainloop    

My intention is to keep the same button to execute button for both the folder_selected and select_individual_file, but the execute button have to identify which input to take by writing the condition or something. Please help.

Answer

You can simply use single global variable and use os.path.isdir() and os.path.isfile() to check whether a folder or a file is selected:

...
import os
from tkinter import filedialog as fd
...

selected_path = '' # initialise the global variable

def select_folder():
    global selected_path
    selected_path = fd.askdirectory()

def select_individual_file():
    global selected_path
    filetypes = (
        ('SQL files', '*.sql'),
        ('All files', '*.*'),
    )
    selected_path = fd.askopenfilename(initialdir='C:/Users/Documents', filetypes=filetypes)

def execute_query():
    if os.path.isdir(selected_path):
        print('Folder selected:', selected_path)
    elif os.path.isfile(selected_path):
        print('File selected:', selected_path)
    else:
        print('No item selected')

...
