So basically I am trying to recreate opening a loot box in Overwatch into a runnable program in python. I'm trying to make it take four random items in an array and display them each time the user types 'open' to open a box. After every box is opened, I want it to loop and ask if they want to open another one, or if they don't and then stop the program. Here's my code so far:

import random# welcome
print("Welcome to the Overwatch Loot Box Simulator!")OpenBox = input("Type 'open' to open a loot box!")OverwatchSkins = ['Legendary: Oni Genji','Epic: Frostbite Pharah','Rare: Banana Winston','Rare: Cobalt Reinhardt','Epic: Synaesthesia Lucio','Legendary: Lone Wolf Hanzo','Rare: Rose Widowmaker','Rare: Celestial Mercy','Epic: Carbon Fiber D.VA','Legendary: Dr. Junkenstein Junkrat','Epic: Nihon Genji','Rare: Blood Reaper','Rare: Ebony McCree','Epic: Demon Hanzo','Rare: Peridot Ana','Rare: Lemonlime D.VA','Epic: Taegeukgi D.VA','Legendary: Mei-rry Mei','Legendary: Augmented Sombra','Rare: Technomancer Symmetra','Rare: Mud Roadhog'
]if OpenBox == "open":print(random.choice(OverwatchSkins))

the OverwatchSkins array would just be filled up with more names later on. Any help is greatly appreciated!

You can wrap everything in a while(True)-Loop and use break to stop the loop, if the user puts in something other than open.

Make sure that only the input and output are in the loop, since you don't want to redefine your list on every pass.

import random
print("Welcome to the Overwatch Loot Box Simulator!")
OverwatchSkins = ['Legendary: Oni Genji', 'Epic: Frostbite Pharah', 'Rare: Banana Winston', 'Rare: Cobalt Reinhardt', 'Epic: Synaesthesia Lucio', 'Legendary: Lone Wolf Hanzo', 'Rare: Rose Widowmaker', 'Rare: Celestial Mercy', 'Epic: Carbon Fiber D.VA', 'Legendary: Dr. Junkenstein Junkrat', 'Epic: Nihon Genji', 'Rare: Blood Reaper', 'Rare: Ebony McCree', 'Epic: Demon Hanzo', 'Rare: Peridot Ana', 'Rare: Lemonlime D.VA', 'Epic: Taegeukgi D.VA', 'Legendary: Mei-rry Mei', 'Legendary: Augmented Sombra', 'Rare: Technomancer Symmetra', 'Rare: Mud Roadhog']while(True):OpenBox = input("Type 'open' to open a loot box! ")if OpenBox == "open":print(random.choice(OverwatchSkins))else:break
