Python- strptime ValueError 未转换的数据仍然存在：:00

Question

我有一个 .csv 文件，其中有一列日期看起来像“2/15/2016 1:44:00 PM”，运行进入以下代码错误...任何人都可以提供有关问题的意见吗？

代码：-

import csv
import datetime as dt
import os

File = 'C:/Users/Alan Cedeno/Desktop/Test_Folder/HiSAM1_data_160215_164858.csv'
root, ext = os.path.splitext(File)
output = root + '-new.csv'
with open(File,'r') as csvinput,open(output, 'w') as csvoutput:

    writer = csv.writer(csvoutput, lineterminator='\n')
    reader = csv.reader(csvinput)

    all = []
    row = next(reader)
    for line in reader:
        row.append(dt.datetime.strptime(line[0],'%m/%d/%Y %H:%M').time())
        all.append(row)

    for row in reader:
        row.append(row[0])
        all.append(row)

    writer.writerows(all)

错误 -

     17             all.append(row)

根据问题中的信息和评论中给出的回溯，您的日期时间格式字符串不完整 - 缺少秒数，应该是：

%m/%d/%Y %H:%M:%S
