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
