Thanks.
Just verified this.

d = {"a":123, "b":34, "c":304, "d":99}

for k, v in d.items():
if k == "a":
print(v)


for k, v in d.items():
if v == 123:
print(k)

several letters with similar count, create a new dictionary with
frequency as keys and values as list of characters with similar
frequencies.

How do you delete an item from a list that is a value in a dictionary?
Dictionary = {'key': [a, b, c, d]}
I want to delete 'b' only. How do I do that?
