def greedy_cow_transport(cows,limit=10):
    train = []
    while sum(cows.values()) > 0:
        cart = []
        total = 0
        for cow, value in sorted(cows.items(), key=lambda x:x[1], reverse=True):
            if cows[cow] != 0 and value + total <= limit:
                cart.append(cow)
                total += value
                cows[cow] = 0
        train.append(cart)
    return train

The code above gives the output:


[['Betsy', 'Henrietta', 'Herman', 'Oreo', 'Millie', 'Maggie', 'Moo Moo', 'Milkshake', 'Lola', 'Florence']]


I want output to be displayed as shown below:

[['Betsy'],
 ['Henrietta'],
 ['Herman', 'Maggie'],
 ['Oreo', 'Moo Moo'],
 ['Millie', 'Milkshake', 'Lola'],
 ['Florence']] 

How to display this way? Is this going to be counted in greedy algorithm?
