Below is the code I am working on. From what I can tell there is no issue, but when I attempt to run the piece of code I receive an error.
import os
import datetime
def parseOptions():
import optparse
parser = optparse.OptionParser(usage= '-h')
parser.add_option('-t', '--type', \
choices= ('Warning', 'Error', 'Information', 'All'), \
help= 'The type of error',
default= 'Warning')
parser.add_option('-g', '--goback', \
type= 'string')
(options, args) = parser.parse_args()
return options
options = parseOptions() now = datetime.datetime.now() subtract = timedelta(hours=options.goback) difference = now - subtract
if options.type=='All' and options.goback==24:
os.startfile('logfile.htm')
else:
print
print 'Type =', options.type,
print
print 'Go Back =', options.goback,'hours'
print difference.strftime("%H:%M:%S %a, %B %d %Y")
print
Error is as followed:
Traceback (most recent call last):

subtract = timedelta(hours=options.goback)
NameError: name 'timedelta' is not defined
Any help would be appreciated.
You've imported datetime, but not defined timedelta. You want either:
from datetime import timedelta
or:
subtract = datetime.timedelta(hours=options.goback)
Also, your goback parameter is defined as a string, but then you pass it to timedelta as the number of hours. You'll need to convert it to an integer, or better still set the type
argument in your option to int
instead.
It should be datetime.timedelta
