我正在嘗試創建一個 Martingale 投注模擬器。我的全局“running_profit”變量應該由“change_running_total”函數間接更新。running_total 變量已正確更新，但受 running_total 影響的 running_profit 變量未更新。import randomround_n = 0bet = 25starting_funds = 5000running_total = starting_fundsrunning_profit = running_total - starting_fundsgoal_profit = 5000wins = 0losses = 0rng_v = 0.00def rng():    """Generates random number"""    global rng_v    rng_v = random.random()def winloss_generator():    """Generates win/loss condition"""    global rng_v    if rng_v <= .49:        return 'win'    else:        return 'loss'def increase_winloss():    """Increases wins or losses variable based on winloss_generator output"""    global wins    global losses    if winloss_generator() == 'win':        wins += 1        return 'win'    elif winloss_generator() == 'loss':        losses += 1        return 'loss'    else:        print('error')def increase_round():    """Increases round number by 1"""    global round_n    round_n += 1    print('round: ', round_n)def change_running_total():    """Increases or decreases running_total based on winloss_generator"""    global running_total    if winloss_generator() == 'win':        running_total += bet    elif winloss_generator() == 'loss':        running_total -= bet    else:        print('error')def print_current_record():    """Prints current win/loss record to screen"""    print('Current Record: ', wins, 'wins, ', losses, 'losses')def print_winloss():    """Prints win/loss condition to screen"""    print(winloss_generator(), 'print_winloss'.upper())def print_profit():    """Print running profit to screen"""    print(running_profit, 'print_profit (variable)'.upper())    print(running_total - starting_funds, 'print_profit (calculated)'.upper())def return_current_funds():    """Returns running total of funds"""    global running_total    return running_total
