How could I check for optional keywords and options in custom command?

[grimlock]

In building a custom command I am trying to validated the presence/absence of an option:

Sample code doing the assignment can be found below

---

results,dummyresults,settings = splunk.Intersplunk.getOrganizedResults()
field = options.get('field', None)

charsense = options.get('detect', None)

Very simply I want to assign none to charsense if the option is not present.
Conversely, I would like to NOT perform character detection if the value is not present.

Additionally, any way to present a usage to the user in the event they do not give either option would be beneficial.

Thank you very much, you guys and gals are always a huge help

Below is the code I ended up using:

For optional keywords:
detect = None
if 'detection' in keywords:
detect = True

For required keywords missing options:
if not options.has_key('field'):
output_result = splunk.Intersplunk.generateErrorResults("Error Message placed here")
