Remove the duplicates from the values list of a key in a dictionary?

Question

Is there a better way to remove the duplicates and only keep the minimum value for each key in my dictionary without looping into the dictionary and without creating a new dictionary to append in it?

dic2 = {}
dic = {0: [4, 4, 4, 4, 5], 1: [3, 4, 4, 4]}
for key, value in dic.items():
    min_value = min(value)
    dic2[key] = min_value
print(dic2)

output

{0: 4, 1: 3}

Answer 1

使用字典理解：

dic2 = {k: min(v) for k, v in dic.items()}

Answer 2

I would be perfectly happy with your solution. The two dictionaries are not the same, they are distinct, so I don't see the benefit in modifying the original. I would reduce by a line though:

dic2 = {}
dic = {0: [4, 4, 4, 4, 5], 1: [3, 4, 4, 4]}
for key, value in dic.items():
    dic2[key] = min(value)
print(dic2)
