python-3.x - 在python中将struct_time转换为String有错误

Question

我20180822使用如下代码运行 my.py 以将 struct_time 转换为字符串

def mkdate(datestr):
    return time.strptime(datestr, '%Y%m%d')

parser = argparse.ArgumentParser(description='Download Images from Web Site')
parser.add_argument('startDate',type=mkdate, nargs='*', help='Start Date to Download')

    if args.startDate:
        startDate = time.strftime('%Y%m%d', args.startDate)

我收到如下错误，虽然我用谷歌搜索但没有任何答案，我该怎么办...

    [time.struct_time(tm_year=2018, tm_mon=8, tm_mday=22, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=2, tm_yday=234, tm_isdst=-1)]
