Print seconds from the epoch including the millisecond

Question

I am using 2.7. I need to print the time in seconds from the epoch with millisecond precision. I have tried many things but have failed.

 from time import time, strftime
 from datetime import datetime, time

 # write date, time, then seconds from epoch
 self.logfile.write('%st'%(strftime("%Y-%m-%d",)))
 self.logfile.write('%st'%(now.strftime("%H:%M:%S",)))
 self.logfile.write('%st'%(now.time()))

What am i doing wrong? What should I be doing here?

Answer 1

In [1]: import time

In [2]: time.time()
Out[2]: **********.1567955
