Answer 1

This should help.

import datetime
s = '2017-11-01T08:11:44.040Z'
#Convert datetime to epoch.
value = (datetime.datetime.strptime(s, "%Y-%m-%dT%H:%M:%S.%fZ") - datetime.datetime(1970,1,1)).total_seconds()
print( value )
#Convert epoch to datetime. 
print( datetime.datetime.fromtimestamp(value) )

Output:

1509523904.04
2017-11-01 13:41:44.040000
