将日期时间格式化为以毫秒为单位的字符串 [英] Format a datetime into a string with milliseconds

问题描述

我想要一个带有毫秒的日期的 datetime 字符串.这段代码对我来说很典型，我很想学习如何缩短它.

I want to have a datetime string from the date with milliseconds. This code is typical for me and I'm eager to learn how to shorten it.

from datetime import datetime

timeformatted= str(datetime.utcnow())
semiformatted= timeformatted.replace("-","")
almostformatted= semiformatted.replace(":","")
formatted=almostformatted.replace(".","")
withspacegoaway=formatted.replace(" ","")
formattedstripped=withspacegoaway.strip()
print formattedstripped

推荐答案

要获取以毫秒为单位的日期字符串(秒后三位小数)，请使用:

To get a date string with milliseconds (3 decimal places behind seconds), use this:

from datetime import datetime

print datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3]

>>>> OUTPUT >>>>
2020-05-04 10:18:32.926

注意:对于 Python3，print 需要括号:

Note: For Python3, print requires parentheses:

print(datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3])
