Python tkinter grid_forget()

Question

I want to make a label appear and disappear, but I am having a problem with grid_forget() . This is part of the code:

def creabackuno():
    showinfo( "Wait..","I am creating the backup, please wait...")
    vsl=Label(gui,text="Working, please wait...",font=("arial",16)).grid(row=20,rowspan=1,column=0,columnspan=1,padx=10,sticky=N)
    try:
        copytree(path,r"backup\dirbackup1\.minecraft")
        showinfo( "OK!","Backup (1) created!")
        vsl.grid_forget()
    except OSError:
        showerror( "Nope!","There is already a backup to restore")
        vsl.grid_forget()

And this is the error of the console:

AttributeError: 'NoneType' object has no attribute 'grid_forget'

Answer 1

You currently have vsl equal to the return value of the grid method of Label . Furthermore, this method always returns None (hence, the NoneType in your error). Make your code like this:

vsl=Label(gui,text="Working, please wait...",font=("arial",16))
vsl.grid(row=20,rowspan=1,column=0,columnspan=1,padx=10,sticky=N)

Now vsl points to the label, not the return value of the grid method, which is None .
