python 字符串到时间转换中的格式错误

Question

When I try to display the string in time, I get a format error.

result3 = ''.join(file_name)


date_time_str = result3

result1 = datetime.datetime.strptime(date_time_str, '%Y-%m-%d %H:%M:%S')





print(result1)

The problem here is that ValueError:time data 20220308233355'does not match format '%Y-%m-%d%H:%M:%S' error occurs. Did I enter the wrong format? I want to mark 20220308233355 as yyyy-mm--dd hh:mm:ss.

Answer 1

yes, you wanna do this:

result1 = datetime.datetime.strptime(date_time_str, '%Y%m%d%H%M%S')
print(result1)

>> 2022-03-08 23:33:55

which is datetime type, if you want string in that format, you have to:

result1 = result1.strftime('%Y-%m-%d %H:%M:%S'))
