Python 代码示例：根据步数计算奖励

您可以使用以下代码来计算奖励：

def calculate_reward(num_steps):
    reward = 0
    if num_steps < TOTAL_NUM_STEPS_1st:
        reward = (TOTAL_NUM_STEPS_1st - num_steps) / (TOTAL_NUM_STEPS_1st - TOTAL_NUM_STEPS_2nd)
    return reward

reward_1st = calculate_reward(TOTAL_NUM_STEPS_1st)
reward_2nd = calculate_reward(TOTAL_NUM_STEPS_2nd)
reward_3rd = calculate_reward(TOTAL_NUM_STEPS_3rd)

print("Reward for 1st step:", reward_1st)
print("Reward for 2nd step:", reward_2nd)
print("Reward for 3rd step:", reward_3rd)

这段代码定义了一个calculate_reward函数，它接受一个num_steps参数，并根据给定的条件计算出奖励。如果num_steps小于TOTAL_NUM_STEPS_1st，则奖励为(TOTAL_NUM_STEPS_1st - num_steps) / (TOTAL_NUM_STEPS_1st - TOTAL_NUM_STEPS_2nd)，否则奖励为0。

然后，我们使用calculate_reward函数计算了1st、2nd和3rd步的奖励，并将结果打印出来。
