>>> old =  {'Georgia': ['18', '13', '8', '14']}
>>> new = {key: list(map(int, value)) for key, value in old.items()}
>>> new
{'Georgia': [18, 13, 8, 14]}

You can do this:

map is taking the values from the iterable in this case the value of the dictionaries key and casting every item in the iterable to an int . map returns a map object instead of a list so we are converting it back to a list.

a_dict = {'Georgia': ['18', '13', '8', '14']}
a_dict['Georgia'] = list(map(int, a_dict['Georgia']))

Or, if you need to convert multiple values this way you can use a loop:

 for k,v in list(a_dict.items()):
     a_dict[k] = list(map(int, v))
