How to sort a dictionary having keys as a string of numbers in Python

Question

I have a dictionary:

a = {\'100\':12,\'6\':5,\'88\':3,\'test\':34, \'67\':7,\'1\':64 }

I want to sort this dictionary with respect to key s

Answer 1

If you install my blist package, it includes a sorteddict type. Then you could simply:

from blist import sorteddict

def my_key(dict_key):
       try:
              return int(dict_key)
       except ValueError:
              return dict_key

a = {'100':12,'6':5,'88':3,'test':34, '67':7,'1':64 }
print sorteddict(my_key, **a).keys()

Output:

['1', '6', '67', '88', '100', 'test']
