updating certain values in dict. with relation to their keys

[ThomasL]

Hi malevy, this is how i understand what you want to do. Is that right?

dictionary = {1: 10, 2: 20, 3: 30, 4:40}

current = 10
found = False

for key, value in dictionary.items():
    if value == current:
        dictionary[key] = value + 3 * key
        found = True

if not found:
    dictionary[current] = current * 2
