How do I look for nonzero values

Question

How do I look for a non-zero value in “things” within python and create flags.

return things

def look_things(self, size)

     things = self.read(size)

     return things

Do you mean a non-zero length of `things`? If not, you need to describe the problem better. Show example values of `things`, and what you want to match. — Barmar, Sep 21 '20 at 19:13
That's the same thing you wrote in the question. If it wasn't clear the first time, saying it again won't help. — Barmar, Sep 21 '20 at 19:38
That was in my original answer, but I changed it because you said you were looking for the length, not a value in an array. — Barmar, Sep 21 '20 at 20:15

Use the len() function to test the length of things.

if len(things) > 0:
    self.clear_timeout_flag()
else:
    self.set_timeout_flag()
