Solve the following python programming problem given the following code:
def _adjust(self, * args) : 
    'Adjust the label position according to the scale.' 
    def adjust_label() : 
        self.update_idletasks () 
        (x, y) = self.scale.coords () 
        if self._label_top : 
            y = (self.scale.winfo_y () - self.label.winfo_reqheight ()) 
else : 
            y = (self.scale.winfo_reqheight () + self.label.winfo_reqheight ()) 
self.label.place_configure (x = x, y = y) 
from_ = _to_number (self.scale ['from']) 
    to = _to_number (self.scale ['to']) 
    if (to < from_) : 
        (from_, to) = (to, from_) 
newval = self._variable.get () 
    if (not (adjust_label <= newval <= to)) : 
        self.value = self._last_valid 
        return 
self._last_valid = newval 
    self.label ['text'] = newval 
    self.after_idle (adjust_label) 

    
    

    Fix the buggy line: if (not (adjust_label <= newval <= to)) :
