# Lottery_Project
|
|
|
|
A Python project to analyze and pick lottery numbers using past draw results to predict future draws.
|
|
|
|
## Usage
|
|
|
|
### Top Level
|
|
```bash
|
|
usage: main.py [-h] {update,record-count,generate-ticket,predict} ...
|
|
|
|
A lottery prediction tool.
|
|
|
|
positional arguments:
|
|
{update,record-count,generate-ticket,predict}
|
|
update Update database records
|
|
record-count Get record counts by table in the database
|
|
generate-ticket Generate a random ticket for the specified game
|
|
predict Predict the next drawing
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
```
|
|
|
|
### Update
|
|
|
|
Scrape the game data from the source site and insert records into the database that are not present. A specific year can be selected as the starting year.
|
|
|
|
```bash
|
|
usage: main.py update [-h] [-y YEAR] [-d]
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
-y, --year YEAR Year to start updates with
|
|
-d, --dryrun Run the update process without actually making any database or API calls
|
|
```
|
|
|
|
### Record Count
|
|
|
|
Return a count of records in each game table. A date to start the count from can be specified.
|
|
|
|
```bash
|
|
usage: main.py record-count [-h] [-f FROM_DATE]
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
-f, --from-date FROM_DATE
|
|
Date from which to base the count on (ex. 2026-01-01). The default value is rule-change for the date when game rules last changed
|
|
```
|
|
|
|
### Generate Ticket
|
|
|
|
Generates a random ticket for the game specified.
|
|
|
|
```bash
|
|
usage: main.py generate-ticket [-h] --game {MegaMillions,Powerball}
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
--game {MegaMillions,Powerball}
|
|
The game to predict the next result for
|
|
```
|
|
|
|
### Predict
|
|
|
|
Due to the lottery drawings being as randomized as possible, generating an accurate prediction is not possible. Many window sizes have been tried during testing
|
|
and none of them have yielded any hopeful results. The same numbers will most likely be generated with the same window size until the sample changes enough to
|
|
cause changes in the selections. A different random seed number is chosen for each run to attempt to combat this behavior.
|
|
cause changes in the selections. A different random seed number is chosen for each run to attempt to combat this behavior.
|
|
|
|
```bash
|
|
usage: main.py predict [-h] --game {MegaMillions,Powerball} [--window-size WINDOW_SIZE] [--test]
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
--game {MegaMillions,Powerball}
|
|
The game to predict the next result for
|
|
--window-size WINDOW_SIZE
|
|
The number of records to use in the prediction model, defaults to 10, use -1 for all records
|
|
--test Use the most recent drawing as a test subject to find the right window_size
|
|
```
|
|
|
|
## Draw Dates
|
|
|
|
Mega Millions drawings are held every Tuesday and Friday. Powerball drawings are held every Monday,
|
|
Wednesday, and Friday. In order to conserve processing cycles, the predictor will only request new data
|
|
if there is the potential for new drawings to collect and save. Powerball can have up to 156/157 drawings
|
|
and Mega Millions can have up to 104/105 drawings per year, depending on how draw dates fall.
|
|
|
|
|
|
## Storage
|
|
|
|
The data will eventually be stored in database tables for faster execution. This will also allow for dynamic
|
|
calls for more data based on the draw dates and last drawing stored locally.
|
|
|
|
### Database Engine
|
|
|
|
Sqlite has been chosen for portability and ease of use.
|
|
|
|
## Historical Info
|
|
|
|
The first Powerball drawing was on April 22, 1992.
|
|
The first Mega Millions drawing was on September 6, 1996. The original name was "The Big Game" and was
|
|
rebranded to Mega Millions in May 2002.
|
|
|
|
However, each game has undergone rule changes that have altered the pool of numbers available for the main
|
|
(white) balls and their respective game balls as well. Due to this, the historical information used to
|
|
analyze the draws should start at the most recent rule change date.
|
|
|
|
**The most recent change for Powerball was on October 4, 2015, when the main ball pool increased from 59 to 69
|
|
numbers and the Powerball pool reduced from 35 to 26 numbers.**
|
|
|
|
**The most recent change for Mega Millions was on April 5, 2025, when the Megaball ball pool was decreased from
|
|
25 to 24 numbers as well as the addition of a 10x multiplier. The existing pool of 70 numbers for the main
|
|
game ball pool was part of changes made on October 28, 2017.**
|

Historical results can be scraped from the web and added to the database from the URLs below. The
|
|
results must be scraped by year. Changing the year in the URLs alters the resultset displayed.
