Q: Increase efficiency of card shuffling program

LiondancerI was wondering how would I make this program faster or perhaps use less memory. I thought about using dictionaries instead of lists as they have faster look ups. I'm not sure how to decrease the memory size of this program. num_cards = input("Please enter the number of cards in the deck: ") de...

@retailcoder, are you there?
3:53 PM
@Malachi sort of - busy day at work :)
4:15 PM
@Malachi: I've just noticed that you now have the Strunk & White badge. :-) Gonna aim for Copy Editor?
@retailcoder: that code that you helped me with is being a little bit of a pill because the variables are sort of global in the context the code is used in so if they use the token twice and the second one doesn't have a first name it returns the previous first name, how do I clear the variable? I have tried setting the array variable to nothing before the end of the script, but it isn't working.
@Jamal, I have had Strunk & white for a while, I love editing! lol. I am going to go for every badge I can get!!!!
@Malachi: Shouldn't take you long to get to 500, then!
@Malachi the VBScript code? I'd have to relook at it..
@Jamal I thought you'd have a little diamond next to your name by now :)
@retailcoder: Not yet. Patience is a virtue. I have already decided on my first act of duty, though (nothing special).
@Malachi just looked at your VBScript again; I had a huge doubt about assigning those strings to null (not very vb-like), have you tried setting them to vbNullString instead? (and then the Coalescefunction should still work)
4:39 PM
@retailcoder: I thought that I would be able to take the setting the strings to nothing out, but I had to switch environments, for some reason they don't like me testing form stuff in Prod, imagine that, who do they think they are???? LOL I think I just need to put that back into the code. setting the name strings to nothing.
anyone care to revisit this question?

@Malachi AFAIK VB6/VBA/VBScript strings are value types, you don't set them to Nothing or Null - assign them to vbNullString instead. @ dev in prod env: chickens...
I am going through the unanswered questions for the SQL tag and noticed that I have answered some of these and I don't think anyone is looking at them, i was hoping that the OP would see that someone answered their questions. most of these people are active on other SE Sites
@retailcoder, I agree! I will try that vbNullString because that seems like the correct practice.
They're chickens. I quick-fix stuff in production all the time, what's the worst that could happen? Everybody in the company on break at the same time?

hey can you tell me if this InStr Function looks correct?
if (isNull(InStr(varPartyName,",")))
FirstMiddleName = ""
MidName = ""
Hmm don't you mean If InStr(varPartyName, ",") <> 0 Then... ? and then FirstMiddleName = vbNullString... - "" and vbNullString are not exactly the same thing, vbNullString takes 0 memory :)
@Malachi InStr returns the index of your comma within varPartyName, 0 if not found.

I assume the Teacher's Lounge is for Moderators? In that case, congratulations :)
