If Statement Not Comparing Properly

As stated, i'm sure this is a simple mistake starting me in the face, but I'm having trouble figuring out why my variable newState, when explicitly set to the string 'F1', does not

Solution 1:

If newstate is F1, it will not trigger the else, because newState != 'F2' will trigger.

In the first if, try making it

if (not(newState == 'F1' or newState == 'F2' or newState == 'F3' or newState == 'error')):

The problem is

if !A or !B or ...

is not the same as

if !(A or B or...)

which is equal to

if (!A and !B and ...)

By DeMorgans law.
