Syntactically, it cannot be a missing comma. Adding the comma is a syntax error.

$ python3 -c 'if datetime.now(),strftime(...) != "19:50:00": pass'
  File "", line 1
if datetime.now(),strftime(...) != "19:50:00": pass
 ^
SyntaxError: invalid syntax

Granted this is a heuristic, but it would be nice if it was able to not suggest 
a change that it would reject as syntactically incorrect.

I concur with Eric: the purpose of the error message is a suggestion based in 
the most likely cause. Also  we have recently refined this so I will trigger in 
less uncommon situations.

period, missing parens, missing brackets, etc.

A human can figure it out based on semantics, but based purely on syntax, I 
think this error message is good enough.

New submission from UnknownLITE :

A dot is missing between `now()` and `strftime` but it is suggesting that most 
probably a comma is missing.
