Using the and operator to check if two values equal a third

[DBS]

Another related question here, I would like to check and see if a value is equal to multiple values using if/or.  Would it be correct to use the statement below?

if a == 'no' or 'yes' or 'maybe':
    do something

if a in ('no', 'yes', 'maybe'):
    do something

Never mind... took me a moment to wrap my head around what was happening

Exactly why I don't think that should be used :p

You think wrong   Fresh Python users get confused by list comprehensions - should those be disavowed too?

Or Pythonic non-boolean bolean expressions - instead of writing long chains of if...elses.
Python is ... Pythonic

BTW, another simple way to check equality of more than one variable - for immutables, like strings, numbers, tuples, frozensets

len(set([a, b, c])) == 1

The first one would work.
The second would always be true regardless of value a if b and c where equal.
The third would be true if b was either a or c

The second statement is wrong - if a is Null, zero or empty: string, tuple, list, dict -  it will be False
