I have a variable called
anime_dictwhich contains a dictionary of lists of objects as shown below.
{'JI2212': ('Inu Yasha', [('year', 1992), ('rating', 3)]), 'EH389J': (Naruto', [('year', 开发者_开发知识库1994), ('rating', 4), ('readers', 3424322)]), 'PPP67': ('Fruits Basket', [('Year', 1999), ('rating', 5), ('readers', 434232), ('chap', 40)])}so the key of the dict is the 1st part ('JI2212' for Inu Yasha), the 2nd part is the name and the last part contains a list of parts. I want to create 2 functions that would 1st get the key from the given name and 2nd get the parts from the given name. the functions would be...
get_key(name) and get_parts(name)for instance
>>>get_key('Fruits Basket') 'PPP67' and >>>get_parts('Inu Yasha') [('year', 1992), ('rating', 3)]
It is possible technically, but i would not recommend you to do that, because it will not be efficient, map is designed to use a key to get a value. In your case i think its better to restuct your data from:
{'JI2212': ('Inu Yasha', [('year', 1992), ('rating', 3)])}
to
{'Inu Yasha': ('JI2212', [('year', 1992), ('rating', 3)])}
then it is very easy to achieve your goal.
There's keys
and values
methods. Use those, do not do it entry-by-entry, it'll be very slow, because search of key by value is linear.
You should really have your key's be the anime names, it makes life a lot easier.
For example, now your dictionary is being inserted like:
anime_dict[id] = (name,...)
A better way would be to do:
anime_dict[name] = (id,...)
Unless you have a specific reason have the key's be id, this way is just generally easier to understand and use.
If you just want to convert your original dictionary to a new one, you can run the following:
old_dict = {'JI2212': ('Inu Yasha', [('year', 1992), ('rating', 3)]), 'EH389J': ('Naruto', [('year', 1994), ('rating', 4), ('readers', 3424322)]), 'PPP67': ('Fruits Basket', [('Year', 1999), ('rating', 5), ('readers', 434232), ('chap', 40)])}
new_dict = {}
for key in old_dict.keys():
name = old_dict[key][0]
data = old_dict[key][1:]
new_dict[name]=(key, data)
Hope it helps!
