Hi, I can run the fine without the race_course function. At the moment it is throwing a type error, and I don't know why!
import random import time
class Horse: def init(self, name, ability): self.name = name self.ability = ability
def score(ability): roll = random.randint(1,6) if roll < ability: return True
def race_course(name, pos): lane = [Horse, '|', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '','', '', '', '', '', '', '', '', '_', '|'] lane.insert(pos, 'H') lane_joined = ''.join(lane) return lane_joined
H_1 = Horse('Colin', 3) H_2 = Horse('Clive', 3)
H_1_pos = 2 H_2_pos = 2
x = True
while x: if score(H_1.ability) == True: H_1_pos += 1
if score(H_2.ability) == True:
H_2_pos += 1
print('\n' * 20)
print(race_course(H_1.name, H_1_pos))
time.sleep(.25)

Also, always use Markdown formatting when posting code (especially Python!).
