dict.setdefault: «am I a joke to you?»

def Tree():
return defaultdict(Tree)

t = Tree()
= 'a'

defaultdict is so useful, I've gotten annoyed at some other languages when their version of a dictionary didn't have an equivalent.

If you try to access a key without adding it to this dictionary, is that key implicitly added (with the default value) or not?

2:04 That's not actually a cast, it's creating a new dict from the defaultdict

Hi there - one thing I use dictionary defaults (I usually use the get function of.a regular function) is for a translation from one representation to another. Often only a few words need to be translated - so the default is the key. For example "american_words={'colour':'color', 'honour':'honor'} then "new_word = american_words.get(word, word)". Is there a way to do this with default_dict?

[TheJaguar]

defaultdict is so invaluable. It's not uncommon for me to subclass defaultdict to override __missingkey__ so that I can use the key in the creation of the default value.

Calamansi (whatever that is - even spell checked did not know it) example works very well with dict() instead of defaultdict()

The true power of defaultdict is allowing you to circumvent your professor’s “No dictionaries” restriction, since it is not a dict = {} 😆
