[TKINTER] Problems creating directories in a selected path

[Vulera]

Thank you for answering my question.

You need to pass the sourcePath

import os
from tkinter import *
import tkinter.filedialog
 
janela = Tk()
janela.title('TESTE')
janela.geometry('200x200')
 
def createDirectory(sourcePath):
    os.chdir(sourcePath)
    directory = 'Data'
    os.makedirs(directory)
 
def selectDirectory():
    sourcePath = filedialog.askdirectory()
    createDirectory(sourcePath)
     
selectButton = Button(janela, text='Select Diretory', width=15, command=selectDirectory)
selectButton.grid(column=0, row=0, padx=10, pady=10)
 
janela.mainloop()
