This is all written in Python 3, and you should be able to run the code without installing any outside libraries (I think!). The most interesting stuff will be in sim.py, which is a module that contains the logic to simulate baseball games. The file params.py has various parameters (stuff like # of innings in a baseball game, number of outs in a half inning, etc.). Note: some of the parameters do not relate to code not in this excerpt. The file misc.py contains miscellaneous helper functions. dirs.py contains information about directories, many of which I have not included. The rest of the files are class declarations.

---------------------------------------------------------------

To run the script

cd into the directory:

drappi_sample/scripts/

and run the command:

python3 main.py sim_games <n>

where n is an integer, representing the number of games you want to simulate.

for example, "python3 main.py sim_games 1000" would simulate 1000 games.

---------------------------------------------------------------

To view results, go to the folder results/

There are three sub-directories. The "pitcher_evs" and "hitter_evs"
contain information about mean box score statistics about players.
The lower case statistic is the player's projection, and the
upper case statistic is the sample average. The two should be pretty close.

The "sims" folder contains scores from games that were simulated.
