Move Python Dictionary From A Dictionary to Another

Question

I am making a game in Python and am storing dictionaries in lists as items:

equipped = {}

swords = {
        'wooden_sword': {'name': 'Wooden Sword', 'dmg': 1}
}

How would I move the wooden_sword item into the equipped lists.

(If i am not using correct terminology feel free to edit)

Answer 1

You can assign the value (actually, a copy of the value) at key 'wooden_sword' in equipped dict to value from swords dict, then delete the value from swords:

...

equipped['wooden_sword'] = swords['wooden_sword'].copy()

del swords['wooden_sword']

print(swords)
print(equipped)

Output:

{}
{'wooden_sword': {'name': 'Wooden Sword', 'dmg': 1}}

If these dictionaries you're moving have more values other than int/str/float (other values such as lists/dicts/...), then consider using deepcopy to copy those inner values as well:

...
from copy import deepcopy

equipped['wooden_sword'] = deepcopy(swords['wooden_sword'])
...

Answer 2

Use something like:

equipped['wooden_sword'] = swords['wooden_sword'].copy()

I'd recommend to put another attribute to the sword instead of moving it, like this:

swords = {
        'wooden_sword': {
            'name': 'Wooden Sword',
            'dmg': 1,
            'equipped': True
        }
}

Like this you can just change an attribute inside 1 dictionary.

Answer 3

Assuming your "equipped" is a dictionary (signified by the fact you used curly brackets) you would do it like this:

equipped.update({'wooden_sword':swords['wooden_sword']})
del swords['wooden_sword']

Answer 4

I'd suggest use a class to keep an instance of the character's items. Then add whatever things you want, like swords, as attributes for that class like so:

class Equipment:
    def __init__(self):
        self.swords = {}

    def add_sword(self, sword):
        self.swords.update(sword)

Then you can have something like:

equipment = Equipment()

sword = {
    'wooden_sword': {'name': 'Wooden Sword', 'dmg': 1}
}

equipment.add_sword(sword)

Of course, you can also turn that sword dictionary into another class for a sword (which again, I recommend). Hope that helps and good luck with your game!
