python轉換為字典中的整數

Question

如何將{'CS2261': '140', 'CS3264': '55'}為{'CS2261': 140, 'CS3264': 55} ？

def everything(file):
    a = {}
    with open(file, 'r') as f:
        for i in f:
            Module,Group,Quota = i.split(',')
            if Module not in a:
                a[Module] = int(Quota)
        return a

Answer 1

你可以像這樣用字典理解來重建字典

d = {'CS2261': '140', 'CS3264': '55'}
print {k: int(d[k]) for k in d}
# {'CS3264': 55, 'CS2261': 140}

Answer 2

{k:int(v) for k,v in d.items()}
