I have a BATCH file that automatically runs my Birthday Pokemon generator indefinitely. It was working fine until I installed Pyenv to down grade my Python to 3.8.10 temporarily to install a specfic module. After reinstalling all the required modules using PIP, the BATCH file stopped looping.

The BATCH file is below, and under is the initial script.

@echo off

python Pokemon.py

:loop
if %ERRORLEVEL% == 0 (
    python Pokemon.py
) else (
    echo Exited with code: %ERRORLEVEL%
    pause
)
goto loop

Pokemon Generator:

#Imports
import pypokedex
import pypokedex.exceptions
import datetime
import os
import json
import random

#Code
birthDate: str = input("Input your birth date n")
birthMonth: str = input("Input your birth month n")
birthYear: str = input("Input your birth year n")
today: datetime.date = datetime.date.today()

year: int = today.year

asking: bool = True

currentDir = os.path.dirname(__file__)
pokemonJson: str = os.path.join(currentDir, "AmountOfPokemon.json")

with open(pokemonJson, "r") as file:
    pokemonData: dict[str, str] = json.load(file)

while asking:
    if len(birthMonth) == 0 or len(birthMonth) > 2 or not birthMonth.isdigit():
        print("input valid birth date.")
        birthDate = input("Input your birth date n")

    if len(birthDate) == 0 or len(birthDate) > 2 or not birthDate.isdigit():
        print("input valid birth date.")
        birthMonth = input("Input your birth month n")

    if len(birthYear) != 4 or not birthYear.isdigit():
        print("input valid birth date.")
        birthYear = input("Input your birth year n")

    if birthDate.isdigit() and int(birthDate) > 31:
        print("input valid birth date.")
        birthDate = input("Input your birth date n")

    if birthMonth.isdigit() and int(birthMonth) > 12:
        print("input valid birth month.")
        birthDate = input("Input your birth month n")

    if birthYear.isdigit() and int(birthYear) > year:
        print("input valid birth year.")
        birthYear = input("Input your birth year n")

    if (len(birthMonth) != 0 or len(birthMonth) <= 2 or birthMonth.isdigit()) and (birthDate.isdigit() and int(birthDate) <= 31) and (birthMonth.isdigit() and int(birthMonth) <= 12) and (birthYear.isdigit() and int(birthYear) <= year):
        asking = False

pokemonNumber = 0

operation = random.randint(1, 2)
number: int = random.randint(1, 50)

if operation == 1:
    pokemonNumber = round( int(birthYear) / (int(birthMonth) + int(birthDate))) + number
elif operation == 2:
    pokemonNumber = round( int(birthYear) / (int(birthMonth) + int(birthDate))) - number

def getPokemonNumber() -> tuple[int, str]:
    global pokemonNumber
    
    print(pokemonNumber)

    if pokemonNumber <= 0 or pokemonNumber > 1025:
        pokemonNumber = 0
        pokemon = "Missingno"
        return pokemonNumber, pokemon
    
    if int(birthMonth) == 7 and int(birthDate) == 1:
        pokemonNumber = 399
        pokemon = "Bidoof"
        return pokemonNumber, pokemon

    try:
        pokemon: pypokedex.Pokemon | str = pypokedex.get(dex=pokemonNumber)
    except pypokedex.exceptions.PyPokedexError:
        pokemon = pokemonData[str(pokemonNumber)] #If getting the POkemon fails due to a network error, fall back to using the JSON file.
    
    if isinstance(pokemon, pypokedex.Pokemon):
        return pokemon.dex, pokemon.name.capitalize()
    else:
        return pokemonNumber, pokemon.capitalize()

playersPokemon: str = getPokemonNumber()[1]
pokemonsNumber: int = getPokemonNumber()[0]

print(f"Your Pokémon is #{pokemonsNumber}: {playersPokemon}, based on your birthday.")

I’ve tried adding a pause at the end of the script. However, pause does not work anymore in BATCH files after installing Pyenv.
