PYTHON 3 (1) Dictionary Python upper case values present in a single key. (2) Why datatype sets in python does not return True element?

Question

(1) A snippet that takes a dictionary and uppercases every value in the dictionary and sets that value back into the dictionary at the same key e.g.

Given:

d = {'a': ['amber', 'ash'], 'b': ['bart', 'betty']}

Result:

{'a': ['AMBER', 'ASH'], 'b': ['BART', 'BETTY']}

(2) Why datatype SET does not return TRUE element when printed? Eg. {'hi', 1, True} returns only {'hi', 1}

For (1) I am using something like this:

 d = {'a': ['amber', 'ash'], 'b': ['bart', 'betty']} 
 d.update((k, v.upper()) for k, v in d.items())

Answer 1

(1)

d2 = {key:[name.upper() for name in names] for key, names in d.items()}

(2)

That seems to be because True == 1 yields True, which is what the Set uses to check if the value added is already in the Set and therefore has to be ignored.
