你可以随时检查它是否超过100,然后再回到原来的位置。然后你从你的主要功能调用movement,说 def playGame():

def playGame():
    position = 0
    while(position != 100):
         position = movement(position)

def movement(current_position):
    distance = random.randint(1,6)
    current_position += distance
          if move > 100:
              current_position -= distance
          else:
              return current_position
