Does anyone know how to get the file save path from this code?

Question

I have a problem with my code. I know the error in the code, but I don't know how to fix it.

The programming language is Python.

This is my project:

from tkinter import *
import os
from tkinter import filedialog


def saveFile():
    file = filedialog.asksaveasfile(defaultextension='.png',
                                    filetypes=[
                                        ("Png file", ".png"),
                                        ("Text file",".txt"),
                                        ("All files", ".*"),
                                    ])
    if file is None:
        return
    filetext = url.get()
    file.write(filetext)
    file.close()


window = Tk()
window.title("Download from browsers")
window.wm_attributes('-toolwindow', 'True')

Tk_Width = 350
Tk_Height = 150
 
positionRight = int( window.winfo_screenwidth()/2 - Tk_Width/2 )
positionDown = int( window.winfo_screenheight()/2 - Tk_Height/2 )
window.geometry("{}x{}+{}+{}".format(330,140,positionRight, positionDown))


urltxt = Label(window, text = "Download Url").place(x = 10, y = 10)  
url = Entry(window, width=30)
url.insert(0,"")
url.grid(row=1, column=0, padx=100, pady=10)

button = Button(text='Save as',command=saveFile)
button.grid(row=2, column=0, padx=100, pady=10)


def startdownload():
    os.system(f"powershell -c \"Invoke-WebRequest -Uri '{url.get()}' -OutFile '{button.get()}'\"")
    os.system("msg * s")

btnSendstartdownload = Button(window, text="download", width=20, command=startdownload)
btnSendstartdownload.grid(row=3, column=0, padx=10, pady=10)

window.mainloop()

The wrong part here

os.system(f"powershell -c \"Invoke-WebRequest -Uri '{url.get()}' -OutFile '{button.get()}'\"")

{button.get()} is the button to save the file path

This is a picture of the program

{button.get()} is supposed to fetch me the file save path

But it shows me an error

I think the problem appears because I am trying to fetch the file path from a button

Does anyone know how to get the file save path from this code?

This is the error message

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Program Files\Python38\lib\tkinter\__init__.py", line 1883, in __call__
    return self.func(*args)
  File "C:\Users\user\Desktop\1\a.py", line 42, in startdownload
    os.system(f"powershell -c \"Invoke-WebRequest -Uri '{url.get()}' -OutFile '{button.get()}'\"")
AttributeError: 'Button' object has no attribute 'get'

Try,

window.filename =  filedialog.asksaveasfile(defaultextension='.png',
                                    filetypes=[
                                        ("Png file", ".png"),
                                        ("Text file",".txt"),
                                        ("All files", ".*"),
                                    ])
file= root.filename 
where window=Tk()

it worked for me.
