Answer 1

use function as command:

def newwindow():
       -----------
   
    
def myexit():
    exit()

def my_command():
    newwindow()
    myexit()
    
    root=Tk()
    signup=Button(root,text="Sign Up",command=mycommand,
                  width=12,bg='green',fg='white',font=("arial",12,'bold'))```
