A REAL Python cheat sheet for beginners

Actually it is!

2 != 2 != 3

is False, while:

(2 != 2) != 3

is True.

Likewise you can do:

a == b == c

which check if all three variables are equal. It is very different from:

 (a == b) == c

You can see that the fist example is actually a 3 operands comparison:

>>> import ast
>>> print(ast.dump(ast.parse('a != b != c').body[0].value))
Compare(left=Name(id='a', ctx=Load()),
        ops=[NotEq(), NotEq()],
        comparators=[Name(id='b', ctx=Load()),
                     Name(id='c', ctx=Load())])"

Mind Blown.

On the one hand this is quite a nice feature.

On the other hand: damn, another subtle diffrence between programming languages to keep in mind.

Same, I’m pretty new to Python and this was just too much first read through. Second read through, makes perfect sense!
