将单个字典值从字符串转换为整数？

Question

Let us consider

set = {'a': '98', 'b': '10', 'c': 'nike', 'd': 'paarudas', 'e': '3'}

I want to change it as,

set = {'a': **98**, 'b': **10**, 'c': 'nike', 'd': 'paarudas', 'e': **3**}.

and one more doubt if i get

set_1 = {'a': '98', 'b': '10', 'c': 'nike', 'd': 'paarudas', 'e': ''}

Then i have to change it to

set_1 = {'a': **98**, 'b': **10**, 'c': 'nike', 'd': 'paarudas', 'e': ''}.

Answer 1

$ python3
>>> s = {'a': '98', 'b': '10', 'c': 'nike', 'd': 'paarudas', 'e': '3'}
>>> {k:int(v) if v.isdigit() else v for k,v in s.items()}
{'a': 98, 'c': 'nike', 'b': 10, 'e': 3, 'd': 'paarudas'}

Answer 2

def int_if_possible(value):
    try: return int(value)
    except: return value

result = dict((k, int_if_possible(v)) for (k, v) in original.items())

Please do not call your variable set ; that is another data type (like dict ).
