Question

我想将时间戳插入到python脚本的输出文件名中，例如：20011231_230159_md5_filelist.csv

我无法插入代码。

这是输出文件名需要时间戳的脚本的 end ：

try:

    my_last_data = get_md5(file_full_path) + ", " + get_last_write_time(file_full_path) + ", " + get_size(
        file_full_path) + ", " + file_full_path + "\n"

    with open("md5_filelist.csv", "a") as my_save_file:
        my_save_file.write(my_last_data)

    print(str(file_full_path) + "  ||| Done")

except:
    print("Error On " + str(file_full_path))

这是我正在与之斗争的时间戳代码（虽然不确定它是否是最适合此目的的行）：

timestr = time.strftime("%Y%m%d_%H%M%S")

我尝试以各种方式插入，不起作用。任何提示？

Answer 1

感谢@ pm-2ring（见评论），解决方案：

timestr = time.strftime("%Y%m%d_%H%M%S")
(timestr + "_md5_filelist.csv", "a")

脚本中的

：

try:

    timestr = time.strftime("%Y%m%d_%H%M%S")

    my_last_data = get_md5(file_full_path) + ", " + get_last_write_time(file_full_path) + ", " + get_size(
        file_full_path) + ", " + file_full_path + "\n"

    with open(timestr + "_md5_filelist.csv", "a") as my_save_file:
        my_save_file.write(my_last_data)

    print(str(file_full_path) + "  ||| Done")

except:
    print("Error On " + str(file_full_path))

这就是你所需要的一切。

try:
    my_last_data = get_md5(file_full_path) + ", " + get_last_write_time(file_full_path) + ", " + get_size(
        file_full_path) + ", " + file_full_path + "\n"

    with open("{}md5_filelist.csv".format(timestr), "a") as my_save_file:
        my_save_file.write(my_last_data)

    print(str(file_full_path) + "  ||| Done")
except:
    print("Error On " + str(file_full_path))

您没有在代码中的任何位置使用timestr。

输入文件名的时间戳
