how to check if there are keys with the same values in a dictionary. python 3.0
for example:
what if there is a list within the values?
because when I try to make it a set, it comes up with an error: unhashable item 'list' .
eg. data = {'size': 4, 'entrance':(0, 0), 'exit':(0,1), 'treasure': [(0, 0)]}
I would like it to return None when there are keys with the same value, but not sure how to check it when some of them are in a list.

Storing data and adding to data in a dictionary: Experiment with Python dictionaries and their keys() member function that returns a list of a dictionary's keys. You can check if a particular key is in a dictionary by using the in test with the keys list. For example, if our dictionary is MyDict = { 1: 'One', 2: 'Two', 3: 'Three' } Then ( 2 in MyDict.keys() ) evaluates to True, indicating that 2 is a valid key for MyDict....

I have a dictionary in which has strings for keys and integers for values. I need to count the length of each key and place it in one of three categories, small, medium or large. Those are defined by: small: length 0-4, inclusive. medium: length 5-7, inclusive. large: length 8+, inclusive. After they are they have been sorted into their appropriate category, the program needs to check which word of each small, medium, large category had the largest key. Sample...

Python 5. Write a function named grade_components that has one parameter, a dictionary. The keys for the dictionary are strings and the values are lists of numbers. The function should create a new dictionary where the keys are the same strings as the original dictionary and the values are tuples. The first entry in each tuple should be the weighted average of the non-negative values in the list (where the weight was the number in the 0 position of the...

PYTHON
Define the remove_e_synonyms() function which is passed a dictionary as a parameter. The keys of the parameter dictionary are words and the corresponding values are lists of synonyms (synonyms are words which have the same or nearly the same meaning). The function removes all the synonyms which contain the letter 'e' or 'E') from each corresponding list of synonyms. As well, the function sorts each corresponding list of synonyms. Note: the testing code makes use of the print_dict_in_key_order(a_dict) which...

1. Define the draw_histogram() function which is passed a Python dictionary as a parameter. The keys of the dictionary are single letters and the corresponding values are integers, e.g., {'b': 5, 'a': 6, 'c': 3}. For each key:value pair in the dictionary the function prints the key, followed by ": ", followed by a series of stars. The number of stars printed is given by the value corresponding to the key. The keys are printed in alphabetical order. Note that...
