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
