What is exit code 1796?

Question

I sometimes get exit code 1796 with no other output, and sometimes it works properly. What is exit code 1796, and is there a way I can fix this?

Edit: I also sometimes get exit code NaN, but neither are very often

I am running this python code:

import random, time #Imports needed functions (Randomizer and time call)

starttime = time.time()

coins = 0

nearbyenemies = []

allenemies = [
#Follows pattern:
#[Level, Name, MinHealth, MaxHealth, MinAttack, MaxAttack, MinArmor, MaxArmor,
#Weakness, Resistance, Special, MinSpecialValue, MaxSpecialValue]
    [1, 'Spike', 10, 15, 3, 5, 0, 0, 'None', 'None', 'Thorns', 3, 5],
    [1, 'Skeleton', 10, 15, 5, 8, 5, 10, 'None', 'None', 'None', 0, 0],
    [1, 'Ghost', 1, 1, 10, 15, 10, 15, 'None', 'None', 'None', 0, 0]
]

def nearby(minlevel, maxlevel, amount, add): #Adds nearby enemies between certain levels
    
    global nearbyenemies
    possibleEnemies = []
    
    if add == True:
        nearbyenemies = nearbyenemies
    else:
        nearbyenemies = []
    
    x = 0
    
    while x < len(allenemies):
        if allenemies[x][0] >= minlevel & allenemies[x][0] <= maxlevel:
            possibleEnemies.append( allenemies[x] )
        x += 1
    
    x = 0
    
    while x < amount:
        nearbyenemies.append( possibleEnemies[random.randint(0, len(possibleEnemies) - 1)] )
        
        x += 1

nearby(1, 1, 2, False)
print(f'Enemies: {nearbyenemies}')

Answer 1

When I run the above code, it finishes with exit code 0:

Enemies: [[1, 'Ghost', 1, 1, 10, 15, 10, 15, 'None', 'None', 'None', 0, 0], [1, 'Spike', 10, 15, 3, 5, 0, 0, 'None', 'None', 'Thorns', 3, 5]]

...Program finished with exit code 0
Press ENTER to exit console.
