Hello lottery players! I hope everyone is doing fine. I was wondering if anyone is aware of a 3 digit lottery program where the user can input and remove up to 900 straight 3 digit combinations from the total and display the remaining combinations at the output?

Thanks in advance.

I just looked at the Positional Wheel Generator and didn't see where I could input a list of straight 3 digit combinations to be removed from the total number of straight 3 digit combinations (1000). Perhaps I am missing something here?

Let's say that I input "123", "234", "345", and "456" to be removed from the total number of combinations(1000). The output should be 996 straight 3 digit combinations minus the 123, 234, 345, and 456 that were removed.

Is there a lottery program that can do that?

The functionality you're asking for is so basic I doubt anyone has created a commercial program that solely removes items from a list and outputs the new shortened list. This is a task you could easily accomplish with your own spreadsheets.

Yes, it appears to be a simple task but i'm having difficulty. I checked out Excel spreadsheets and was totally confused by it. I studied BASIC programming many years ago so i'm vaguely familiar with flowcharts. It appears to be an input, remove, and print output program to me. I'm trying out a program that's new to me called PYTHON. I had a problem using 3 digit combinations with PYTHON because it won't accept combinations with a zero as the leading digit. I probably need to take a class in Excel so I can better understand this new technology.

I do a lot of programming in Python and Sage for math applications. With Python, you need to pass the Pick 3 combos as strings in order to preserve the leading 0. I would do something like this to first generate a list of all the combos and store it as the variable named P3:
```
P3 = []
```
```
for i in range(1000):
```
```
    p = str(i)
```
```
    while len(p)<3:
```
```
        p = "0" + p
```
```
    P3.append(p)
```
Now you have all the combos stored as strings in a list called P3. If you want to remove the combo 806, you run the command

P3.remove("806")

with the quotes, because it's a string. If you then print P3, it will return the list without 806. The remove function only takes one argument, so if you want to remove several combos, you need to run that command many times. That's something you can easily do in a loop.

Thanks! I can't wait to try it out. In the meantime, I wish you and yours a Happy Valentine's Day!

You've been immensely helpful and I appreciate your expertise. I've gotten as far as the output and removing one item, but i'm confused as to how to create a loop. I've been reading about loops and maybe i'll come up with something. Again, many thanks.

This site https://www.geeksforgeeks.org has tons of examples of all kinds of Python code snippets you might need as you build your project. Usually when I google "how to do blah blah blah in python" this is one of the first sites that comes up and the code example is on point.

This is a free course https://www.codecademy.com/learn/learn-python-3 that uses mini projects to help you learn the foundations. The paid options are for people who want a certificate of completion. Supposedly it's only 25 hours to complete. I helped someone work through it a few years ago so I don't know what's changed in that time or if 25 hours is an accurate estimate, but as I remember it was a pretty solid freebie option and the mini-projects had enough complexity that one learned fairly well how to integrate lots of different skills.

This only takes a few columns in Excel

Column A containing all 1000 Combinations can be created with a simple +1 Formula. (you can format the combinations to show leading 0 values to make it look better.

A Box (Range of cells} containing the numbers to be eliminated

Column B use the formula "IF(Countif(Range of Cells,A1)=1,"",A1) If the number in A1 is in the Box the cell is blank. If not the Number appears.

To Condense the list use the formula Small($B$1:$B$1000,A1) in Column C.

You can clean out the Errors by using a IF(A1>Count(B$1:B$1000),"",Small($B$1:$B$1000,A1))
