def convert_seconds(seconds):
    hours = seconds // 3600
    minutes = (seconds - hours * 3600) // 60
    remaining_seconds = seconds - hours * 3600 - minutes * 60
    return hours, minutes, seconds, remaining_seconds

hours, minutes, seconds = convert_seconds(5000)

函数返回四个变量...

return hours, minutes, seconds, remaining_seconds

...但您只获取其中三个值：

hours, minutes, seconds = convert_seconds(5000)

解包时需要包括所有值：

def convert_seconds(seconds):
    hours = seconds // 3600
    minutes = (seconds - hours * 3600) // 60
    remaining_seconds = seconds - hours * 3600 - minutes * 60
    return hours, minutes, seconds, remaining_seconds

hours, minutes, seconds, remaining_seconds = convert_seconds(5000)

您的函数返回4个值：小时、分钟、秒、剩余_秒
在您的函数调用中，您正在解包3个值：小时、分钟、秒
因此，您需要解包的值太多，正确的方法是解包4个值：
hours, minutes, seconds, remaining_seconds = convert_seconds(5000)
