Hi all!

I am trying to merge 3 lists, without success.

titles = ['Mario','Luigi']
prices = ['10','1']
descriptions = ['Mario is cool!','Luigi is boring :(']
game_list = []

for idx, val in enumerate(titles):
    game_list.append([titles[idx], prices[idx], descriptions[idx]])

Open in new window


What am I doing wrong?

Don't see at the first glance what's wrong. Will copy your code and try it. Next time you should provide the exact error message or the exact behavior. It makes it easier to locate the problem.

Python has a built in function to do exactly this:
game_list = zip(titles, prices, descriptions)

Open in new window



Modification:
I tried your code and it seems to combine the three lists into one list containing  sublists.

titles = ['Mario','Luigi']
prices = ['10','1']
descriptions = ['Mario is cool!','Luigi is boring :(']
game_list = []

for idx, val in enumerate(titles):
    game_list.append([titles[idx], prices[idx], descriptions[idx]])

print(game_list)

Open in new window


The output is:
[['Mario', '10', 'Mario is cool!'], ['Luigi', '1', 'Luigi is boring :(']]

Open in new window


Is this not what you want?

Please show us the expected reslut If you want to combine the three lists differently.
