Re: [Tutor] Formating from hhmms to hh:mm:ss

Title: Signature.html

Yep, I tried strptime and strftime but got stuck too often on something or other (mostly mixing time, datetime somehow), so simplified matters to make it clear what I was trying to do. I'm sure you have the essence below, but I'm not familiar with the In/ Out notation. Apparently, I need to scoop up the In lines into a file and add some print stmts for the In[x] d lines. Here's what I think I should put in a py file and the results: # Using datetime to do date-time math on a file date-time stamp and # the creating the new stamp from datetime import datetime, timedelta format = '%Y%m%d_%H%M%S' d=datetime.strptime('20080321_113405', format) print d datetime.datetime(2008, 3, 21, 11, 34, 5) d += timedelta(seconds=200) print d datetime.datetime(2008, 3, 21, 11, 37, 25) print d.strftime(format) Results: Traceback (most recent call last):   File "C:/Sandia_Meteors/Improved_Sentinel/Sentinel_Playground/Utility_Dev/debugDateTime.py", line 6, in ?     d=datetime.strptime('20080321_113405', format) AttributeError: type object 'datetime.datetime' has no attribute 'strptime This attribute problem is reminiscent of my problems.

You can do what you want much more simply using datetime.strptime() and strftime(): In [2]: from datetime import datetime, timedelta In [3]: format = '%Y%m%d_%H%M%S' In [8]: d=datetime.strptime('20080321_113405', format) In [10]: d Out[10]: datetime.datetime(2008, 3, 21, 11, 34, 5) In [13]: d += timedelta(seconds=200) In [14]: d Out[14]: datetime.datetime(2008, 3, 21, 11, 37, 25) In [15]: d.strftime(format) Out[15]: '20080321_113725' Kent -- Wayne Watson (Watson Adventures, Prop., Nevada City, CA) (121.015 Deg.
