[Python] Is there a way to fix this UnboundLocalError: local variable referenced before...

I have attempted to add a points system to this F1 game which updates after each race to eventually be ranked. However, even after referencing each driver's points at the start (second block), the function 'def race_result()' still says that they are undefined, although I am expecting each driver's points variable to change after each race. This is the error on its own:

redbull_performance=1800
Verstappen_pts=0 # defined here
def race_result():
Verstappen=95+redbull_performance+random.randint(1,1000)
drivers=[Verstappen]
pts=[0,25,18,15,12,10,8,6,4,2,1,0,0,0,0,0,0,0,0,0,0,0]
drivers.sort(reverse=True)
position=0
print("Race")
print("")
print(" # Driver Team Country Pts")
for i in range(20):
if drivers[position]==Verstappen:
r1="Max Verstappen Oracle Red Bull Racing - NED -"
Verstappen_pts+=pts[position # can't find Verstappen_pts variable
position+=1
if position<10:
print("",position,r1,pts[position])
else:
print(position,r1,pts[position])
race_result()

**Traceback (most recent call last):

UnboundLocalError: local variable 'Verstappen_pts' referenced before assignment**


This is the full code - it worked perfectly before the points system:
