To access the value of 'teddy bear' in your nested dictionary, you can follow these steps:
First, you access the 'soft toys' category by using its key:
soft_toys = nested_favorite_toys['soft toys']
Then, you access the 'teddy bear' inside the 'soft toys' category by using its key:
teddy_bear_material = soft_toys['teddy bear']
Finally, you print out the material of the teddy bear:
print(teddy_bear_material)
When you run this code, it will print out cotton
, which is the value associated with 'teddy bear' in your nested dictionary. It's like finding a specific toy in a box within a bigger toy chest! π§Έπ¦
Absolutely, let's dive into Python dictionaries with some fun examples!
Dictionaries are like a special kind of toy chest where each toy has a name tag. You can find your toy by looking at its name tag instead of searching through the whole chest.
Here's how you can create a dictionary of your favorite toys with their names:
In this dictionary,
favorite_toys
, each toy has a name (like 'teddy bear') and a description (like 'soft').Accessing Items: To find out what your teddy bear is made of, you can look at its name tag:
This will print out
soft
, because that's the description for your teddy bear.Changing Items: If you want to change the material of your teddy bear to something else, you can do that too!
Now, when you print
favorite_toys
, it will show{'teddy bear': 'cotton', 'robot': 'metallic', 'puzzle': 'wooden', 'doll': 'plastic'}
. Your teddy bear's material is now cotton!Adding Items: If you get a new toy and want to add it to your dictionary, you can do that!
Now, when you print
favorite_toys
, it will show{'teddy bear': 'cotton', 'robot': 'metallic', 'puzzle': 'wooden', 'doll': 'plastic', 'car': 'plastic'}
. You've added a car to your dictionary!Removing Items: If you decide to give away one of your toys, you can remove it from your dictionary.
Now, when you print
favorite_toys
, it will show{'teddy bear': 'cotton', 'robot': 'metallic', 'puzzle': 'wooden', 'car': 'plastic'}
. The doll is no longer in your dictionary!Looping Through Dictionaries: You can look at each toy and its description in your dictionary one by one using a loop.
This will print out each toy and its material on a new line.
Copying Dictionaries: If you want to make an exact copy of your favorite toys dictionary, you can do that too!
Now
all_my_toys
is an exact copy offavorite_toys
.Nested Dictionaries: You can also have a dictionary inside another dictionary. It's like having a big toy chest with smaller boxes inside it.
In this nested dictionary,
nested_favorite_toys
, we have two categories of toys: soft and hard. Each category has its own box with toys inside.Remember, dictionaries are like a special kind of toy chest where each toy has a name tag. You can find your toy by looking at its name tag instead of searching through the whole chest! π§Έπ€π§©ππππͺ
