Strange, it gives me an error message when i type result["jordan"] or result[max(result)] though :

>>> results = { 
  "gengyang": 14, 
  "ensheng": 13, 
  "jordan": 12 
} 

>>> result["jordan"]
Traceback (most recent call last):
  File "<pyshell#27>", line 1, in <module>
    result["jordan"]
NameError: name 'result' is not defined

>>> result[max(result)]
Traceback (most recent call last):
  File "<pyshell#28>", line 1, in <module>
    result[max(result)]
NameError: name 'result' is not defined
>>>
