how to determine if a tuple doesnt has an empty input Python

Question

I'm simply trying to determine if my tuple has empty inputs. I'm reading Data from an Excel Sheet and it gives tuples in the form

(3,4,6), (3,4,7)

so basically it typically has 3 parameters but there are some cells that don't include the first or second parameter, so technically it would be

('','',6)

In my code I have set up as:

for i in range(len(self.listOfTuples)):
    for j in range(len(self.listOfTuples[i])):
        if(self.listOfTuples[i][j][0] == '' or self.listOfTuples[i][j][1] == ''):
            print("GOT IT ")

and it's not printing my statement, when I print out the self.listofTuples[i][j][0]. It actually prints out nan, but when I change my if statement with "nan" it still doesn't print out my statement. Is there something i'm missing ?

Any time you find yourself iterating over range(len(something)), you're doing it wrong. Iterate over the thing itself. — Daniel Roseman, Dec 03 '18 at 22:11
`None` and `nan` are _very different_ beasts. This question is not a dupe. It should be reopened. — DYZ, Dec 03 '18 at 22:12
Isn't the problem rather [checking for NaN values?](https://stackoverflow.com/questions/944700/how-can-i-check-for-nan-values) — Thierry Lathuille, Dec 03 '18 at 22:12
yeah maybe so but the question that you linked to is a little different from what I asked. Plus I had already seen that post previously that's why I decided to post my own question — Jeff Pernia, Dec 03 '18 at 22:20
@DYZ no worry , just take times to find the dup for me . :-) — BENY, Dec 03 '18 at 22:21

nan is "not-a-number". You can detect it with math.isnan(self.listOfTuples[i][j][0]).

so if the value is "nan" would it spit out true and if not false ? – Jeff Pernia Dec 03 '18 at 22:14
Correct. And the `nan` that you see is actually `float("nan")`. – DYZ Dec 03 '18 at 22:14
awesome it worked . – Jeff Pernia Dec 03 '18 at 22:18
