목록에서 [NaN]을 삭제하는 방법?

Question

나는 내가 얻을 모든 [NaN]의 삭제하려면 어떻게

a = [[u'63764'], [u'63764'], [u'63764'], [u'70272'], [u'98362'], [u'NaN'], [u'NaN']] 

을 다음 있습니다 :

a = [[u'63764'], [u'63764'], [u'63764'], [u'70272'], [u'98362']] 

당신에게

Answer 1

사용 math.isnan 수 NaN 여부를 확인하기 :

>>> NaN = float('nan') 
>>> import math 
>>> math.isnan(1) 
False 
>>> math.isnan(NaN) 
True 

list comprehension로 :

>>> [xs for xs in a if not any(math.isnan(x) for x in xs)] 
[[1], [1], [2], [2], [2], [3], [3]] 

UPDATE

질문 편집에있어서

>>> a = [[u'63764'], [u'63764'], [u'63764'], [u'70272'], [u'98362'], [u'NaN'], [u'NaN']] 
>>> [x for x in a if x != [u'NaN']] 
[[u'63764'], [u'63764'], [u'63764'], [u'70272'], [u'98362']]
