如何在Python中动态嵌套现有字典？

Question

I have a program that can ask user to categorize and existing dictionary: here is my dictionary:

>>> print Vocab_World
{'excelent': 'awesome', 'quit': 'exit', 'great': 'good', 'ceken': 
'bilir', 'tremendous': 'fabolous', 'gurbet': 'hasret', 'postpone': 
'put_offt', 'ozlem': 'hasret'}

Now I want to ask the user if they want to categorize the same meaning words as nested dictionary and I want to have a list like below one for the categorized words

{'Adverb' : {'excelent': 'awesome','great': 'good','tremendous': 'fabolous'} }

.

categorized_words = raw_input("Please select the words that you want to categorize")
new_category = raw_input("Please input the new category name ")
categorized_World=Vocab_World[new_category][0][categorized_words]

Is there a way of doing that dynamically based on user input ?

Answer 1

Vocab_World = {'excelent': 'awesome', 'quit': 'exit', 'great': 'good', 'ceken': 
'bilir', 'tremendous': 'fabolous', 'gurbet': 'hasret', 'postpone': 
'put_offt', 'ozlem': 'hasret'}

Categorized_World = {}  # output dict
chosen_words = []       # array to store all the chosen words

while True:
    categorized_words = raw_input("Words to categorize separated by ',' or Q/q for quit)")
    if categorized_words.lower() == 'q':
        break
    chosen_words.extend(categorized_words.split(','))
    new_category = raw_input("Please input the new category name ")
    Categorized_World[new_category] = {i:Vocab_World[i] for i in
                                       categorized_words.split(',') if i in Vocab_World}

# Add words that are not catgorized
Categorized_World.update({i:Vocab_World[i] for i in Vocab_World if i not in chosen_words})

print(Categorized_World)

Running this and inputing:

excelent,great,tremendous
adverb
q

Would return:

{'adverb': {'excelent': 'awesome', 'great': 'good', 'tremendous': 'fabolous'}, 
'quit': 'exit', 'ceken': 'bilir', 'gurbet': 'hasret', 
'postpone': 'put_offt', 'ozlem': 'hasret'}

Answer 2

This should do it:

Vocab_World= {'excelent': 'awesome', 'quit': 'exit', 'great': 'good', 'ceken': 
              'bilir', 'tremendous': 'fabolous', 'gurbet': 'hasret', 'postpone': 
              'put_offt', 'ozlem': 'hasret'}

categorized_words = raw_input("Please select the words that you want to categorize ")
new_category = raw_input("Please input the new category name ")

Categorized_World=dict()
tmp=dict()
for w in categorized_words.split():
  tmp.update({w:Vocab_World[w]})

Categorized_World.update({new_category:tmp})
print Categorized_World

Output is:

Please select the words that you want to categorize excelent great tremendous
Please input the new category name Adverb
{'Adverb': {'excelent': 'awesome', 'tremendous': 'fabolous', 'great': 'good'}}
