Dictionary using distinct characters as values

I need to make a dictionary using the string list as keys and their distinct characters as values.

I have tried some functions and ended up with the following code but I cannot seem to add the string key into it 

value=["check", "look", "try", "pop"]
print(value)
def distinct_characters(x):
    for i in x:
        yield dict (i=len(set(i)))
print (list(distinct_characters(value))

I would like to get 

{ "check" : 4, "look" : 3, "try" : 3, "pop" : 2}

but I keep getting 

{ "i" : 4, "i" : 3, "i" : 3, "i" : 2}
Solution

  • Well, string is itself an iterable, so don't call list on dicts instead call dict on list of tuples like below.

    value=["check", "look", "try", "pop"]
print(value)
def distinct_characters(x):
    for i in x:
        yield (i, len(set(i)))
print(dict(distinct_characters(value)))

    Output:

    {'check': 4, 'look': 3, 'try': 3, 'pop': 2}
