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

Title: Signature.html
Well, maybe. Here's the file the change and 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)
d = datetime.datetime(*(time.strptime('20080321_113405', format)[0:6]))
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 7, in ?
    d = datetime.datetime(*(time.strptime('20080321_113405', format)[0:6]))
AttributeError: type object 'datetime.datetime' has no attribute 'datetime'

>From a PLEAC web:
# The easiest way to convert this to a datetime seems to be; 
now = datetime.datetime(*time.strptime("16/6/1981", "%d/%m/%Y")[0:5])
# the '*' operator unpacks the tuple, producing the argument list.
I tried the [0:6] and it got the same results.

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.
    

Kent uses IPython, which is an enhanced version of the standard python
shell.  That's what the In[] and Out[] bits are from.

This attribute problem is reminiscent of my problems. IDLE? Python 2.4.x?
    

Python 2.4, unfortunately.  datetime.strptime only came in with Python
2.5, IIRC.  The Python 2.4 version is:

d = datetime.datetime(*(time.strptime(date_string, format)[0:6]))

(i.e. that corresponds to "d = datetime.datetime.strptime(date_string, format)")
