如何通过使用python为其分配一个值来将纪元转换为日期时间？

Question

how to convert epoch to time by assigning a particular epoch value to it. tried assigning values to a and calling it. couldnt able to do it.

import datetime

a=1529396478000

datetime.datetime.fromtimestamp(a).strftime('%c')

Answer 1

import datetime

a=1529396478000
a /= 1000

print(datetime.datetime.utcfromtimestamp(a).strftime('%Y-%m-%d %H:%M:%S'))

Answer 2

try datetime.datetime.fromtimestamp(a).strftime('%Y-%m-%d %H:%M:%S')

I think a is missing a dot, a=1529396478.000 otherwise the year is 50434 resulting in a ValueError.
