Delete a CTk label

[Prajwal201011]

So I have been trying to delete a CTk Label using .delete function but it doesn't work
does anyone know how to do it

`
def cal():
princip = int(p.get())
Term = int(t.get())
Rate = int(r.get())
amt = (principTermRate)/100
amtl = CTkLabel(interest, text=f"Amount is: {amt}")
amtl.pack(pady= 15)

def clear():
    amtl.delete(0, 'end')
    
btnc = CTkButton(interest, text="Clear", fg_color="#1dc444", command=clear())
btnc.pack(padx=5, pady=5)`
