How to access the values of a nested dictionary structure

Question

I have a nested dictionary structure and I want to iterate through it and print the values of each key within the nested key. For example:

    animals = {
        "Bear": {"food": "fish", "claws": "12"},
        "Tiger": {"food": "meat", "claws": "8"},
        "Elephant": {"food": "grass", "claws": "0"},
        "Chicken": {"food": "feed", "claws": "talons"},
        "Wolf": {"food": "rabbits", "claws": "6"}

    }

target_animal = "Tiger"
tfood = ?
tclaws = ?
print("A tiger's food: "+ tfood)
print("A tiger's claws: "+ tclaws)

I have tried iterating through

if inner dictionary name == target_animal: 
    for i in kingdom.keys():
        #print(i)
        for j in kingdom[i]:
            innerDict = (kingdom[i][j])

I do not know where to check for: if the inner dictionary name = "tiger", nor how to only access the values at the targeted inner dictionary.

The goal is to iterate through the 'animals' dictionary and if the key == the target_animal, print its inner dictionary values.

Answer 1

You just have to chain the brackets :

animals = {
        "Bear": {"food": "fish", "claws": "12"},
        "Tiger": {"food": "meat", "claws": "8"},
        "Elephant": {"food": "grass", "claws": "0"},
        "Chicken": {"food": "feed", "claws": "talons"},
        "Wolf": {"food": "rabbits", "claws": "6"}

}

target_animal = "Tiger"
tfood = animals[target_animal]["food"]
tclaws = animals[target_animal]["claws"]

In the code above, you have animals[target_animal] which is equivalent to {"food": "meat", "claws": "8"}. This is itself a dictionary, so you can add the ["food"] and ["claws"] to access the value whitin.

Answer 2

animals = {
        "Bear": {"food": "fish", "claws": "12"},
        "Tiger": {"food": "meat", "claws": "8"},
        "Elephant": {"food": "grass", "claws": "0"},
        "Chicken": {"food": "feed", "claws": "talons"},
        "Wolf": {"food": "rabbits", "claws": "6"}

    }
# if you just wanna query for one animal, then
target_animal = "Tiger"
target_dict = animals['Tiger'] 
#dtype of target_dict again is a dict, so you can #again use indexing
tfood = target_dict['food']
tclaws = target_dict['claws']
print("A tiger's food: "+ tfood)
print("A tiger's claws: "+ tclaws)

If you want to iterate through everything

for animal, props in animals.items():
    print(f"A {animal}'s food: {props['food']}")
    print(f"A {animal}'s claws: {props['claws']}")

If you want to use iteration and still filter out only for tiger, then

for animal, props in animals.items():
    if animal=='Tiger':
        print(f"A {animal}'s food: {props['food']}")
        print(f"A {animal}'s claws: {props['claws']}")
