Hint:

>>> def demo():
...     fake_data = ['n/a', 'n/a', 'n/a', 'n/a', '[omitted]', '12']
...     fake_result = not all(i == '[omitted]' for i in fake_data)
...     print 'This is fake result: ', fake_result
... 
>>> demo()
This is fake result:  True
>>> from numpy import all
>>> demo()
This is fake result:  False
