从有序列表中的键排序字典值

Question

Say I have the following dictionary:

FruitValues={'Banana':3, 'Orange':4, 'Apple':1}

And I have a list of the keys of this dictionary in a order that I want to preserve:

SortOrder=['Orange', 'Apple', 'Banana']

What is the most efficient way of getting a list of the values from the dictionary in the order of the list?

Right now my approach is the following:

OrderedValues=[]
for Fruit in SortOrder:
    OrderedValues.append(FruitValues[Fruit])
print OrderedValues

[4, 1, 3]

Is there a better / cleaner way of doing this? Maybe using a dictionary comprehension?

Answer 1

Use list comprehension:

>>> [FruitValues[i] for i in SortOrder]
[4, 1, 3]
