How to convert a python function (with parameters) into a standalone executable?

Question

I have a python pandas function that uses some libraries and takes in a couple of parameters. I was wondering if it is possible to convert a python function with parameters to an application (so, .exe file). Would pyinstaller do the trick in this case?

Here is the code for my function:

import math
import statistics
import pandas as pd
import numpy as np
from scipy.stats import kurtosis, skew
from openpyxl import load_workbook

def MySummary(fileIn, MyMethod):
    DF = pd.read_csv(fileIn)
    temp = DF['Vals']
    
    if (MyMethod == "mean"):
        print("The mean is " + str(statistics.mean(temp)))
    elif (MyMethod == "sd"):
        print("The standard deviation is " + str(temp.std()))
    elif (MyMethod == "Kurtosis"):
        print("The kurtosis is " + str(kurtosis(temp)))
    else:
        print("The method is not valid")

What will happen if this gets converted to an .exe file. Will it automatically request arguments for the function MySummary or something like that?

Answer 1

using the argparse module

import argparse

...
if __name__ == "__main__":
    parser = argparse.ArgumentParser(description="Calculate stats: mean, sd, Kurtosis")
    parser.add_argument('fileIn', help="input .csv file")
    parser.add_argument('MyMethod', help="stats method")
    args = parser.parse_args()
    MySummary(args.fileIn, args.MyMethod)
