How to compare two time fields in python

I have to compare two time field strings represented like "[email protected]@EDT". How can i compare them most optimally in python?

I want to do >= type comparsions on such fields which are of type string.

val1 = "[email protected]@EDT"
val2 = "[email protected]@EDT"

if val1 > = val2:
    <do something>

import datetime    
t=datetime.datetime.strptime("[email protected]@EDT","%Y%m%d@%H%M%S.%f@%Z")

datetime object supports direct compare using >=.

standard python lib may not handle timezones well ,you may need some third-party module like pytz

Something like the following should do the trick.

import time

val1 = "[email protected]@EDT"
val2 = "[email protected]@EDT"

a = time.strptime(val1, '%Y%m%d@%H%M%S.%f@%Z')
b = time.strptime(val2, '%Y%m%d@%H%M%S.%f@%Z')
if a >= b:
    <do something>

import time
from time import gmtime, strftime
currentTime=strftime("%Y-%m-%d %H:%M:%S", gmtime())
print currentTime
time.sleep(5) 
SecondTime=strftime("%Y-%m-%d %H:%M:%S", gmtime())
print SecondTime
from dateutil.parser import parse
parseSecondTime = parse(SecondTime)
parseCurrentTime = parse(currentTime)
diffOfTime = parseSecondTime - parseCurrentTime
timeDifference=diffOfTime.total_seconds()
print timeDifference
if timeDifference>0:
    print 'SecondTime is greater'
else:
    print 'Current Time is Greater'

Use the datetime module for this.

Use datetime.datetime.strptime to convert the strings into dates then compare them using >=.
