I'm working on my first python script, which creates and updates and object with different datetime entries.
I'm setting up the object like this:
# Date conversion
import datetime
import time
# 0:01:00 and 0:00:00 threshold and totalseconds
threshold = time.strptime('00:01:00,000'.split(',')[0],'%H:%M:%S')
tick = datetime.timedelta(hours=threshold.tm_hour,minutes=threshold.tm_min,seconds=threshold.tm_sec).total_seconds()
zero_time = datetime.timedelta(hours=0,minutes=0,seconds=0)
zero_tick = zero_time.total_seconds()
format_date = '%d/%b/%Y:%H:%M:%S'
from datetime import datetime
# Response object
class ResponseObject(object):
def __init__(self, dict):
self.__dict__ = dict
# JSON encoding
from json import JSONEncoder
class MyEncoder(JSONEncoder):
def default(self, o):
return o.__dict__
# > check for JSON response object
try:
obj
except NameError:
obj = ResponseObject({})
...
entry = "14/Nov/2012:09:32:31 +0100"
entry_tz = str.join(' ', entry.split(None)[1:6])
entry_notz = entry.replace(' '+entry_tz,'')
this_time = datetime.strptime(entry_notz, format_date)
# > add machine to object if not there, add init time
if not hasattr(obj, "SOFTINST"):
#line-breaks for readability
setattr(obj, "SOFTINST", {
"init":this_time,
"last":this_time,
"downtime":zero_time,
"totaltime":"",
"percentile":100
})
...
print this_time
print MyEncoder().encode({"hello":"bar"})
print getattr(obj, "SOFTINST")
My last 'print' returns this:
{
'totaltime': datetime.timedelta(0),
'uptime': '',
'last': datetime.datetime(2012, 11, 14, 9, 32, 31),
'init': datetime.datetime(2012, 11, 14, 9, 32, 31),
'percentile': 100,
'downtime': 0
}
Which I cannot convert into JSON...
I don't understand why this:
print this_time #2012-11-14 09:32:31
but inside the object, it's stored as
datetime.datetime(2012, 11, 14, 9, 32, 31)
Question:
How do I store datetime objects in "string format" and still have them easily accessible (and modifyable) in Python?
Thanks!
