First time poster...need help with a snippet

First mistake. You can't remove items while iterating through them.
Example. First thing you should notice it doesn't print them all.

def main():
    item_list = [
    'Heart of Gold', 'Rod of Ages', "Rabadon's Deathcap", 'Guardian Angel',
    'Bloodthirster', 'Ionic Spark', "Mejai's Soustealer"
    ]

    item_list2 = item_list[:] # shallow copy

    # Show error
    for i, item in enumerate(item_list):
        print(item)
        # remove every odd one
        if i % 2 == 1:
            item_list.remove(item)

    print()
    print(item_list)

    # build another list
    dump_list = []
    for i, item in enumerate(item_list2):
        if i % 2 == 1:
            dump_list.append(item)

    print()
    print(dump_list)
    for item in dump_list:
        item_list2.remove(item)

    print(item_list2)
main()

1. Use random.choice over random.randint(0, 1)
2. Use for loop and range over while. for counter in range(len(item_list)).

Only look at this. If you want to see how I would do it.

Hide/Show

import random

def on_death(item_list):
    number_of_items = len(item_list) / 2
    items_to_destroy = int(number_of_items + (number_of_items % 2) * 0.5)

    for counter in range(items_to_destroy):
        choice = random.choice(item_list)
        item_list.remove(choice)

def main():
    item_list = [
    'Heart of Gold', 'Rod of Ages', "Rabadon's Deathcap", 'Guardian Angel',
    'Bloodthirster', 'Ionic Spark', "Mejai's Soustealer"
    ]

    on_death(item_list)
    print(item_list)

main()
