python - Python NameError，我无法理解

Question

我现在正在练习定义函数：

def get_seconds(hours, minutes, seconds):
    return 3600*hours+60*minutes+seconds

现在，我想执行这个函数：

amount_a = get_seconds(7200*minutes+30*seconds)
amount_b = get_seconds(__)
result = amount_a + amount_b
print(result)

错误：

NameError: name 'minutes' is not defined

Answer 1

首先你定义“get_seconds”函数，你只需要：

amount_a = get_seconds(hours=2, minutes=30, seconds=0)
amount_b = get_seconds(hours=0, minutes=45, seconds=15)
