Replacing values from one set with values from another, if the value of set1 = the key of set2?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

EDIT: Changed dictionaries to Sets, as I had not realised {} denoted a set. And fixed to say that sets are included in a tuple.



I want to iterate through each set in cardTuple, and for each value, replace it with the corresponding value(face) from imageDict. I assume we match value with with index, and somehow output the face. Maybe I need a third set or list to store results in before outputting?



imageDict = dict() # Contains index:face and looks like 1 👽 2 🐕 3 🐱 4 🚑 5 🚓 6 🐼 7 🐶 8 🐸 9 🐴 10 🐰 11 🐭 12 🐬 13 🐢 14 🐝

cardTuple = ({7, 42, 15, 47, 20, 52, 25, 30}, {3, 39, 14, 47, 55, 22, 23, 31})


My current approach:



newList = 
newList2 =
for i in cardTuple:
for j in i:
if i == 1: ## maybe this needs to be 0?
newList.append(imageDict[j])
elif i == 2: ## maybe 1?
newList2.append(imageDict[j])


Any advice?

    @Karim: To be clear, the meaning of curly braces ({}) depends on their content. If they're empty, or they store key-value pairs separated by colons (:), they're a dict. If they're non-empty, but don't have a colon in them, they're a set.

Firstly, as mentioned in the comments, dict1 is not a dict. It is a set. But you probably meant for it to be a list.
Here's a simple way to get what you want using list comprehensions:



mylist = [1,5,7,10,13]
mydict = {
1:face1,2:face2,3:face3,4:face4,5:face5,6:face6,7:face7,
8:face8,9:face9,10:face10,11:face11,12:face12,13:face13
}

output = [mydict[key] for key in mylist]

>>> [face1, face5, face7, face10, face13]





share|improve this answer
























  • So with output, you're creating a new list but I don't understand how the comparison works with "for key in mylist". Maybe you could explain what mydict[key] is doing? Is it comparing mydict key with key in mylist? If so, is it automatic that it outputs the value?

    – Karim
    Nov 16 '18 at 15:11

    mydict[key] is extracting the value (face1,face2...) based on the key provided. In this case, the item in mylist. In this example it's essentially creating a list of mydict[1], mydict[5], mydict[7]... based on mylist = [1,5,7...]

    dict objects are a collection of key: value pairs. By saying mydict[key] I am accessing the value associated with that key. By doing this in a for loop in a list comprehension, I am creating an output list type where each entry is the value associated with each key in mylist. You might want to look up list comprehensions - they are very useful Python constructions.
